Most trail shoe problems (black toenails, heel slip, knee pain on descents) come down to fit. We match the shoe to your foot, not the other way around.

Common questions about trail shoe fit

How do I find the right trail running shoe for my feet?
Use Wayfinder's free fitting tool. Answer a quick quiz about your running style, terrain, and preferences, then scan your feet with your phone for millimeter-accurate measurements. The algorithm matches you to 3–5 shoes from 120+ models across brands like Salomon, HOKA, Brooks, and Altra. The whole process takes about 5 minutes.
Why do my trail running shoes cause black toenails?
Black toenails are almost always a fit issue, not a size issue. If the toe box is too roomy, your foot slides forward on downhill sections and your nails take the impact. If it's too narrow, the nail beds are compressed directly. Wayfinder's 3D scan measures your exact toe box width and shape so recommendations account for this dimension specifically.
What is the difference between trail running shoes and road running shoes?
Trail shoes have stiffer midsoles, deeper lugged outsoles, and fit geometries designed for uneven terrain. Road shoes are built for flat, forward motion. Using road shoes on technical trails increases ankle roll risk. Wayfinder matches you to shoes built for your specific conditions: rocky, rooty, technical, or flowy.
How accurate is the phone-based 3D foot scan?
The scan captures millimeter-accurate measurements of foot length, width, arch height, volume, and heel shape. You place your bare foot on a white background and hold your phone steady. The scan takes about 60 seconds and no special equipment is needed beyond your smartphone.
Is the trail shoe fitting tool free?
Yes, completely free. The quiz, 3D foot scan, and personalized recommendations are all free. No account is required to start. When you're ready to buy, you go directly to our partner retailers at normal retail prices.
Does this work if I have wide, narrow, or flat feet?
Yes — this is exactly where Wayfinder adds the most value. Standard shoe sizing doesn't account for width, arch height, or foot volume. The 3D scan captures all of these dimensions, so the algorithm can match you to shoes with the right geometry for your specific foot shape. Many wide-foot and flat-arch runners find trail shoes through standard sizing that cause friction or instability because the fit geometry is wrong even when the length is right.
