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 (Altra Lone Peak 9 (Men's)) and Alpinetrek (Salomon Thundercross). "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.
