Athlete-inspired and built for speed, this is the Arc'teryx® Sylan Pro shoe for mountain runners looking to move faster on technical trails. The midsole's rocker geometry drives propulsion and is made from InFuse, a light, highly responsive EVA and Polyolefin composition that provides rebound and absorbs shock. The grippy Vibram Megagrip outsole uses LITEBASE technology to shed weight without sacrificing performance, and aggressive lugs deliver a confident bite. The fit locks tight, and a knit collar seals out debris. Polyester upper, cotton lining, and EVA insole. Lace-up closure. Padded tongue and collar. Branding on the side. Low-top design.Round toes.
