Verdict
The Salomon X Ultra 4 GTX is a high-performing option in its class — a day hiking low scoring 89/100 in SoleHunt's data-driven evaluation, drawing on 0 consumer reviews and 0 independent expert tests. Tipping the scales at 360g, it is on the heavier side for a day hiking low. The 28mm heel stack — a moderate stack — delivers a firm ride at 40 HC, returning 50% of impact energy and feeling moderately responsive underfoot. Geometrically, the X Ultra 4 GTX runs on a high 11mm drop that cushions the transition for heel strikers, with a 17mm forefoot stack that maintains the traditional heel-elevated geometry runners with tight calves often prefer. Fit-wise, the toebox measures 98mm — roomy, with space for wider feet and swelling on long runs — and the upper comes in a standard width. True to size. Gore-Tex adds slight stiffness initially. It is designed for day hikes, wet conditions, technical trails, multi-day trips, and performs less well for casual walks or hot dry conditions.
