Run. Train. Travel. How it Fits: Customers who reviewed this shoe suggest sizing up a 1/2 size. Breathe. The Interval Knit AF is a minimalist cross-trainer for athletic performance in a clean, casual style and sock-like comfort. Traditional knit shoes can often fit loose and cause the foot to migrate during lateral movements. Our TightKnit™ upper combined with internal thermal harness keeps your foot supported and in place. Lightweight and responsive, the Cross Platform outsole has a bias towards training yet maintains excellent running performance. Unisex Sizing: 10.5 Mens Upper Material: TightKnit™ / Ripstop Color: Phantom Black / Speckle Off-White / Gum Style: STC7FW015-PGU Reposhed Very little wear, recently purchased and only worn to try on.
