The result is a shoe that keeps you light on your feet but is still tough enough to help you tackle the long run. Breathable mesh upper with internal bootie construction for a snug, sock-like fit that moves with you. FLEXFILM seamless overlays add lightweight support and lockdown. RUNDRY collar lining wicks away sweat to keep feet dry and fresh. Internal strap system wraps the midfoot for added support where you need it most. EVA+ high-abrasion foam midsole for durable cushioning mile after mile. New to the Kivara 8, an EVERUN Topsole adds responsive energy return with every step. 4mm offset provides a more natural running experience, relying on the strength of your foot to power each stride. Durable XT-900 carbon rubber in high-wear areas of the outsole for durable traction where you need it most without slowing you down with unnecessary weight. Wider lugs allow greater ground contact and flexibility, helping to grip the ground at impact, then propel you forward into your next stride. Wt. 7.9 oz.
