These are two different kinds of shoe.
The Salomon Thundercross is a trail running shoe; the Salomon X Ultra 4 GORE-TEX is a low hiking shoe. The lighter one saves 200 g a pair, but they are built for different kinds of hiking, so the lightest is not automatically the better buy.
What the extra 200 g of the Salomon X Ultra 4 GORE-TEX buys you
- A waterproof membrane (GORE-TEX), so wet grass, puddles and rain stay outside.
What the Salomon Thundercross offers besides the lower weight
- No membrane, so it breathes better in the heat and dries faster after a stream crossing.
Weights are per pair as Alpinetrek lists them, usually for a medium size, so a few grams either way can come from the size they weighed. The other specs were checked on 19 October 2026 against Alpinetrek (Salomon Thundercross) and Alpinetrek (Salomon X Ultra 4 GORE-TEX). "Not stated" means the source does not mention it, not that the shoe lacks it. List prices are the full price shown by that source, not a sale price; where sources disagree we show none.
Choose the Salomon Thundercross if…
…you move fast on trails, run some of it, and want the lightest and most flexible shoe; it gives little ankle support under a heavy pack.
Choose the Salomon X Ultra 4 GORE-TEX if…
…you want a sturdier sole and more protection than a trail runner for day hikes and lighter backpacking, without the weight of a boot.
