The Saucony Kinvara 8 is a light but very stable running shoe. Kinvara 8 has new upper design that is flexible and forgiving. The heel hold and grip around the ankles has been increased and the general fit of the shoe is more premium and will provide a responsive feel. The Saucony Kinvara is traditionally a lighter / faster category running shoe that might not last the expected 800 km’s if used by large-ish runners. Kinvara 8 is a new breed of Kinvara. A full length EVERUN topsole construction has beefed up the cushioning and also increased the durability of Kinvara 8. The EVERUN topsole is a resilient cushioning layer that does not compress over time like so many cushioning systems, providing a noticeable improvement to the feel of the shoe during long runs and as you reach the end of its life.
