There are several types of stabilizing footbeds (Conform’able and Sole Custom are two) as well as prescription orthotics. The ones I use are Superfeet footbeds. They have a hard plastic and cork rear and midsection that holds the heel in place, minimizing foot movement and overpronation. There are two types: off-the-shelf footbeds, called Trim to Fit, and Custom Fit. Trim to Fit footbeds can stabilize the foot 40 to 75 percent, and Custom Fit ones stabilize it up to 95 percent. Due to my level of overpronation, I wear Custom Fit Superfeet. To make these, the fitter holds the foot in the neutral position (footbeds made with the feet weighted will fit the overpronated foot, which you don’t want). The footbeds, which are partially shaped already, are heated and then held under your feet in plastic bags. All the air is then sucked out of the bags—a slightly peculiar sensation—while the footbeds mold to your feet.
Since your feet are so firmly supported and no longer move in your footwear, stabilizing footbeds can feel strange and even uncomfortable at first. It may be a good idea to wear them for just a few hours at a time until you adjust, though I could wear them all day immediately. Once the footbeds are fitted they can be transferred from one pair of shoes or boots to another, and I now put them in all my footwear. I now take a smaller size because my feet no longer elongate much when weighted. I can stride off my toes too, rather than the insides of my feet, so I’ve lost that slightly splayed duck-footed walk I had. My feet ache less because the footbeds prevent the cushioning fat pad under the heel from flattening and spreading sideways when weighted, and my knees ache less on long descents because my ankles, knees, and hips are properly aligned.
BREAKING IN
Gone, thankfully, are the days when you had to wear boots for many short, gentle strolls before you dared subject your feet to them on a real walk. Today you can set off on a fifteen-mile walk the same day you buy a pair of lightweight boots and suffer not a blister; for medium-weight models a short break-in period is advisable, though not essential. Only if you have particularly tender feet or heavyweight boots (which I don’t recommend) will you need to wear your boots for a long time before setting off on a major trek. Old-fashioned remedies like soaking your boots and then walking them dry or filling them with hot water were designed for old-fashioned stiff leather. This brutal treatment probably didn’t do boots much good in the old days, and it would certainly harm modern boots.
To test your alignment, stand with your feet slightly apart and your hands held out in front of you, one over the other. Have a friend slowly press down on your hands. If you overpronate you’ll lose your balance quickly and feel very unstable. Next stand on a pair of stabilizing footbeds and repeat the test. With your joints properly aligned, you should be able to resist the downward pressure without much effort.

To demonstrate the fat pads, get a friend to push her fingers against the base of your unsupported heel. She should be able to feel the heel bone easily. Then have her squeeze the sides of the heel together with the other hand and press with her fingers again. This time the fat pad will prevent her from feeling the bone. Stabilizing footbeds do the same. If your feet don’t overpronate, these tests won’t show much difference, and you won’t need stabilizing footbeds.
Volume Adjusters and Tongue Depressors
Stabilizing footbeds will have an effect only if your footwear fit properly. If they are too roomy, the footbeds alone won’t stop your feet from moving in them. For that you’ll need to reduce the boots’ volume by wearing thicker socks; by putting a solid, noncompressible flat piece of neoprene, called a volume adjuster, under the footbed; or by placing a piece of soft rubber under the laces to push the tongue down on the foot when the laces are tightened (a tongue depressor). These methods can make boots and shoes with too high a volume fit better, but it’s best to have a good fit to start with. Luckily that is easier than it used to be. Since Phil Oren’s FitSystem came to prominence, some boot-makers have altered the shape of their lasts and reduced the volume of their footwear so they are more like most people’s feet. Certainly I more often find footwear that fits well.
The Right Fit
Once your feet have been inspected and measured and the fitter has decided whether you need stabilizing footbeds or other accessories, it’s finally time to try on some footwear. It’s best to wear your hiking socks for this. Don’t, even now, expect to find a perfect fit: as close as possible is what you’re looking for, meaning a boot that approximates the shape of your foot in volume and width as well as length. Beware of boots that are too big. These tend to feel comfortable because they don’t press anywhere on your feet, but in use they’ll rub and be unsupportive. Boots should fit snugly around the heel, ankle, and instep but have room for you to wiggle your toes. They should flex at the same point as your feet do so you don’t have to fight them every time you take a step, which is tiring and may make your feet slip inside your footwear.
Incline Board
Once you’ve found a rough fit, you need to try the boots on a 20-degree ramp known as an incline board. Lace the boots firmly, then stand facing up the board while the fitter checks that the boot heels fit properly and sees whether there is any space or loose fabric around the instep and ankle, showing that the boot has too much volume. The fitter should also mark on the boots with chalk or a piece of tape the points where they flex and, by feeling for the first metatarsal head at the base of your toes, check whether your feet flex in the same place. Once this is done, you face down the incline board and jump up and down before the fitter again checks to see if your feet have moved much in the boots. If they have, the boots have too much volume. This can be solved as described earlier, but it is preferable to try lower-volume footwear instead.
Modification
The footwear that fits your feet best is still unlikely to fit exactly. A good fitter should be able to modify footwear to achieve a custom fit. Pressure points, often around the flex point, are the main problem. Boots can be stretched to remove them, using the blunt end of a bent metal rubbing bar to gradually ease out the leather or fabric. Just a tiny modification can have quite an effect on the fit. Since I test boots for a hiking magazine, I have my own rubbing bar at home so I can stretch boots that are too narrow for me. This has let me test many boots that would otherwise have hurt my feet. Occasionally there may be tiny bumps inside footwear due to manufacturing anomalies. With the boot on the rubbing bar, these can be flattened with a convex hammer.

Although leather can be stretched on the rubbing bar, you can’t stretch hard, synthetic toe boxes and heel counters or rubber rands (see under Footwear Materials and Construction below) without heating them first to soften the material. This can be done by sealing the boots in a plastic bag and dunking them in a large pot of boiling water. Various hydraulic devices can then be used along with the rubbing bar to stretch the boots.
For the fit that is closest to perfect, you can have casts made of the front or rear of your foot and then inserted into footwear to stretch it to the exact shape of your feet. Although initially expensive, the casts can be used for all your footwear.
A good boot fitter should make any required modifications when you buy footwear. If you already have footwear that doesn’t fit properly, you can take it to a store to be modified. Phil Oren believes that most footwear needs modification of some sort to get the best fit.
I suggest going through the fitting process every time you buy new hiking footwear even if it is the same model. Manufacturing processes can change, and new lasts may be used. I’ve found that models that once fitted me well didn’t do so a few years later. I discovered that a different factory was producing them and that the fit had indeed changed slightly. If you keep the details of your foot examination and measurements, this
process doesn’t need to be done every time, though it’s worth an occasional check to see if anything has changed, especially if you have any foot problems. It’s advisable to always fit footwear using any accessories you expect to use with them, such as stabilizing footbeds.
When you get your new footwear home, wear them inside for a few hours or even a few days just to check that they really do fit. A store should exchange footwear that haven’t been worn outside. Once they’re muddy and scuffed, they’re yours.
FOOTWEAR MATERIALS AND CONSTRUCTION
There are two basic parts to a boot or shoe: the uppers, which are flexible and mold around the foot; and the sole, which is more rigid and lies under the foot. The sole is usually made up of a number of layers. The insole lies under the footbed and is usually quite thin. The midsole lies between the insole and the outsole and may itself consist of several layers of shock-absorbing and stiffening materials. The outsole contacts the ground and has a tread cut into it. The uppers and the sole are made separately and then attached via the construction method.

Uppers
Leather
Leather is still the main material for uppers, though synthetics now dominate midsoles and linings and fabric-leather combinations are standard for running and trail shoes and common in the lightest boots. Leather lasts longer than other upper materials, keeps your feet dry longer, and absorbs and then disperses moisture (sweat) quickly and efficiently. It is also flexible and comfortable.
Although fancy names abound, there are two basic types of leather: top-grain and split-grain. Top-grain leather, made from the outer layer of the cow’s hide, is tougher and thicker and holds water-repellent treatment and its shape better than split-grain leather, which is the inner layer of the hide. Split-grain leather is often coated with polyurethane or polyvinyl chloride (PVC) to make it more water resistant and attractive. However this shiny layer soon cracks and allows the leather to soak up water like a sponge, while the remaining coating impedes drying. Full-grain leather is the full thickness of the hide. It’s very tough and water resistant but also thick and heavy, so it’s rarely used in boots, although the term is often used for top-grain leather. Nubuck (also spelled nubuc and nubuk) is top-grain leather that has been sanded and polished to give it a smooth finish somewhat similar to suede. It’s much tougher and more water resistant than suede, which is split leather with the inner surface turned outward and brushed. Nubuck is popular with bootmakers because it shows scuffs and scratches less than smooth leathers do and has a sensuous feel. Some top-grain leather boots have the rough inner surface of the leather facing out, though this is less common now that nubuck is available. Rough-out and nubuck leathers are easily distinguished from suede by their thickness and solidity. Suede is often used to strengthen the wear points of fabric footwear. Although it is not as durable, supportive, or water resistant as top-grain leather or the best split leathers, good-quality suede is still worth considering for lightweight footwear.
Leather comes in various thicknesses, always measured in millimeters—inches just aren’t precise enough. Heavyweight mountaineering boots usually have 3-millimeter leather, light hikers 2-millimeter or less.
To make it usable in footwear, all leather has to be tanned—treated with chemicals or oils. With some leathers a water-repellent substance—usually silicone—is chemically bonded to the fibers during tanning. This leather goes by various names, such as HS12, Prime WeatherTuff, and Pittards WR100. I’ve found that this leather performs as advertised, especially when new, and is nearly waterproof. In time, though, the waterproofing breaks down and waxing (for more on this, see Waterproofing and Sealing later in this chapter) is required.
Fabric-Leather
Many lightweight boots and trail shoes copy the nylon-suede design of the running shoes they were based on. This works well in all but the coldest, snowiest conditions. Uppers are mostly fabric, often nylon mesh in shoes but usually textured nylon in boots (though sometimes polyester), reinforced with leather, suede, or synthetic leather. This design requires many seams, which are vulnerable to abrasion and thus may not be durable in rough, rocky terrain, where boot uppers take a hammering. (I found this out the hard way many years ago while scrambling and walking on the incredibly rough and sharp gabbroic rock of the Cuillin Ridge on Scotland’s Isle of Skye. After two weeks, my nylon-suede boots were in shreds, and virtually every seam had ripped open.)
WET FEET/DRY FEET
One reason many people wear leather boots is to keep their feet dry. On weekend hikes, many boots will indeed do this, at least when they’re fairly new. But on longer trips it becomes more difficult; on walks of several weeks it’s impossible if the rain lasts many days. This is because leather boots need to be fully dried and then treated with a waterproofing compound after a few wet days if they are to keep your feet dry. Boots with waterproof linings need less care, but they have other disadvantages (see pages 56 and 58).
On a long walk in wet weather, completely drying any kind of boot material is very difficult. I walked 1,300 miles up the length of Norway and Sweden during a very wet summer. Because much of the route was over rough terrain, I wore lightweight leather boots. For most of the walk they were sodden, which doubled their weight, reduced the breathability, and softened the leather so it gave less support. I would have been far better off with fabric-leather shoes, which wouldn’t have gained as much weight when wet, would have been much more breathable, and would have dried more quickly when it wasn’t raining. My feet would still have been wet, but they’d have been much more comfortable. I’d rather have cool, wet feet than hot, sweaty feet.
In warm weather, wet feet aren’t a problem—as long as you can keep them dry overnight. When it’s cold, the answer is thick socks, preferably with a high wool content, changed regularly. During a forty-day walk through wet, thawing spring snow in the High Sierra, my heavy leather boots were soaked most of the time. (If I did that trip again, I’d ski and wear plastic boots.) By the end of each day, my wool socks were soaked. To keep my feet as warm and dry as possible, I alternated two pairs of thick wool socks, hanging the previous day’s wet socks on the back of my pack to dry each morning and wearing the pair I’d dried the day before. I kept a third dry pair for wearing in the tent. It worked—I had no blisters or other foot problems during the walk. An alternative for wet weather is a pair of waterproof-breathable socks (see pages 78–79). These will keep your feet dry and are, in my opinion, a far better choice than footwear with waterproof-breathable linings.
Waterproofness is not a strong point of fabric-leather footwear either, unless they are lined with a waterproof-breathable membrane. This is again mostly because of the seams but also comes from the thinness of the materials. Grit and dirt can penetrate nylon much more easily than leather, however, so such membranes do not last as long in synthetic boots as in leather boots, whether they are lightweight nylon or the much tougher Cordura. I like synthetic leather for trail shoes, but for lightweight boots I prefer all leather since I wear boots only in terrain I feel is too rugged for shoes.
So why consider fabric-leather footwear at all? Because it’s cool in warm weather (as long as there’s no membrane), it needs little or no breaking in, it’s comfortable, and it dries more quickly than heavier footwear. It’s also used on many of the lightest, most flexible shoes.
Synthetic Leather
Many sandals, some shoes, and a very few boots (such as the Garmont Vegan) use synthetic leather for the uppers, often in combination with nylon. Synthetic leather is flexible and mimics fairly well the performance of split-grain leather, though not top-grain. It has the advantage of being nonabsorbent and therefore quick drying, but it’s not very breathable.
Plastic
Plastic is now the dominant material for mountaineering boots, alpine ski boots, and telemark ski boots because it’s better than leather at providing the rigidit
y, waterproofness, and warmth such pursuits require. But hiking boots need to be flexible and permeable to moisture so that sweat can escape. I’ve hiked in plastic telemark and climbing boots, and I’ve never had such sore and blistered heels or such aching feet. With their rigid soles and outer shells, such boots work against your feet rather than with them. Now when I hike to the snow in my plastic telemark boots, I undo the clips on the uppers to allow my feet to flex. This isn’t very stable, but it’s less painful than keeping the boots done up. Plastic hiking boots have appeared in the past but soon vanished, since they were too hot and sweaty.
Heel Counters and Toe Boxes
Heels need to be held in place and prevented from twisting, and toes need room to move and protection from rocks and other natural protuberances. Heel counters, or heel cups, are stiff pieces of material—usually synthetic, though sometimes leather—built into the rear of boots or shoes to cup the heels and hold them in place. You usually can’t see them, although some makers put them on the outside of some footwear, but you can feel them under the leather of the heel. Heel counters are essential. A soft, sloppy heel without a counter won’t support your ankle, no matter how high the upper.
Toe boxes are usually made from similar material inserted in the front of a boot; some boots dispense with this construction in favor of a thick rubber rand around the boot toe.
Linings and Padding
Traditionally, linings were made from soft leather—as they still are in some boots—but lighter, less-absorbent, harder-wearing, quicker-drying, moisture-wicking, nonrotting synthetics are taking over. The main one is Cambrelle. I find these new linings superior to their leather counterparts (unless the boots have waterproof-breathable membrane linings, as discussed below, in which case leather protects the membrane better). Some wearers have found an odor problem with synthetic linings, but that hasn’t occurred in the footwear I’ve used.
