The Salomon X Ultra 5 Mid GORE-TEX is the boot narrow-footed hikers most often land on, and the lab data explains why. RunRepeat cut the X Ultra 5 in half and measured the widest part of the toe box at 93.0 mm, a millimeter under the 94.0 mm category average, with the big-toe zone at 71.2 mm, and its user poll reports the boot running slightly small. That is the profile of a trim, precision-fit last rather than a dramatically skinny one: snug through the midfoot and instep, close over the toes, with none of the dead air that lets a narrow foot slide. Salomon's SensiFit construction wraps the midfoot from the sole up into the lacing, so cinching the laces actually narrows the interior around a slim foot instead of just squeezing the tongue.
Underfoot, the X Ultra 5 pairs a notably firm single-density midsole, measured at 54.7 on RunRepeat's durometer, about 16 percent firmer than the outdoor-boot average, with the Advanced Chassis, a TPU brace between foot and outsole that RunRepeat measured at 22.8 Nm of torsional rigidity. For narrow feet that combination matters more than it does for most hikers: a foot that fits close to the platform, held by a stiff chassis, does not roll or shear sideways on off-camber terrain the way it can in a roomier, softer boot. Owner reports consistently describe the boot as planted and precise on technical ground, from switchback descents to loose scree.
GORE-TEX waterproofing is standard, and at roughly 15.4 ounces per shoe in a men's 9 (RunRepeat lab weight; the women's version is lighter at about 13.8 ounces), it is among the lightest waterproof mids in its class. The women's X Ultra 5 Mid GTX is sold in the regular fitting only, which for this page is the useful direction: Salomon's women's last is already trim, and it is the men's side that adds an optional Wide. If your feet run wide rather than narrow, that Wide version is covered in our mirror guide to the best hiking boots for wide feet.
The limitations are the flip side of the strengths. The firm ride is less forgiving than a cushioned trail shoe over a long day, the synthetic upper will not mold to your foot the way the leather boots below do, and there is no dedicated Narrow fitting, so hikers whose heels still lift after a surgeon's knot should look at the LOWA Renegade Narrow next. But as the default first try for a narrow foot, combining a trim last, lab-verified stability, GORE-TEX, and a fair $185 price at every major retailer, the X Ultra 5 Mid is the strongest overall pick among the best hiking boots for narrow feet in 2026.
