The ProGrid Virrata is Saucony's lightest and most flexible running shoe. Built on a 0mm offset that keeps the heel and forefoot at the same level so you feel like you're running barefoot, this shoe lets your feet do the work while still providing plenty of cushioning and protection from the road. Breathable Mono mesh upper with internal bootie construction, HydraMAZ collar lining, and reflective details. High abrasion EVA+ midsole. XT-900® outsole with Triangular Lug design. Wt. 6.0 oz.
