The Escalante Racer is even faster, higher performance version of the Escalante. The upper is firmer, highly breathable and has a lighter heel counter for optimum cornering and comfort on the race course. To top it off, the Altra EGO midsole is a touch firmer for a little more energy return and a little less cush. Each limited edition version is inspired by a major city and only available surrounding its respective marathon. Hot! Best Women’s Road Running Shoes
