The latest update of the Saucony Kinvara stays true to its roots while introducing a couple new features. The Kinvara 12 remains a highly versatile shoe that is a great lightweight everyday trainer for efficient runners or a great racing shoe for distances up to the marathon. A firmer ride is given some additional responsiveness through the updating of the “topsole” to PWRRUN+, while the midsole continues to be regular PWRRUN — a nice blend of EVA and TPU. A new, distinctive flared heel is designed to even out impact forces and the upper dispenses with unnecessary overlays in favor of a lightweight, “vanish-on-the-foot” engineered mesh. This is a distraction-free shoe. A new gusseted tongue design supplies padding just where you need it. The outsole is primarily blown rubber, but is more durable than past models. If you are looking for a lightweight neutral trainer that you can do everything in, the Kinvara is one to try.
