You want a nimble, lightweight trail shoe for fast short-distance racing. Heavy 350g platform weight hinders quick turnover on fast singletrack and sprint finishes.
You are unaccustomed to zero-drop footwear and run steep mountain climbs. Zero-drop geometry places high eccentric stretch on Achilles tendons on steep ascents.
You have narrow, low-volume feet that slide inside wide toe boxes. Original FootShape fit provides massive internal volume that can feel loose on narrow feet.
