Catalogue weights; a matching weight basis has not yet been confirmed. The other specs were checked on 19 October 2026 against Alpinetrek (Saucony Xodus Ultra 4) and Alpinetrek (Topo Athletic MTN Racer 4). "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.
