The 5th edition of the Kinvara features a ProLock lacing system for an adaptable, dynamic midfoot fit. The collar has been redesigned for more plush comfort, and the upper features a more durable mesh. Despite these upgrades, the weight stays consistent at a feathery 6.7oz (size 8)! Features include a FLEXFILM upper that locks in the fit without adding weight, and iBR+ midfoot outsole pods for smoother transitions. 4mm offset/22mm heel/18mm forefoot. This shoe was voted Runner’s Choice in the Runner’s World Fall Shoe Guide for 2014.
