Same kind of shoe, so weight is a fair tiebreaker.
Both are trail running shoes. The Kiprun Kipsummit Max is 104 g a pair lighter than the Inov-8 TrailFly Ultra G 280.
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 (Inov-8 TrailFly Ultra G 280) and Alpinetrek (Kiprun Kipsummit Max). "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.
