The Kinvara 6 comes in sporting a new open and breathable mesh. Combine this with a Pro-Lock lacing system and you'll feel the wind in your toes while enjoying a secure midfoot fit. Adjustments in the upper deliver an even more dialed-in fit while maintaining the same weight as its predecessor. The internal bootie provides a sock-like feel. The RUNDRY lining wicks away moisture for a dry, comfortable run. POWERGRID in the heel provides cushion upon foot strike. High-abrasion EVA+ in the midsole is lightweight and durable. iBR+ pod added to the midfoot delivers a smoother transition. Highly durable XT-900 carbon rubber is used in high-wear areas of the outsole.
