We’ve refined the already popular HIIT XT both in fit and function. The construction is more durable and more flexible for not only a better feel, but a better running experience. The updated lacing system improves stability and enhances support for lifting along with any lateral movements you choose to perform.
Places your heel and forefoot the same distance from the ground to encourage proper, low-impact form throughout your run.
