Our Pulse XT is geared to enhance your boldness. It's more dynamic than any training shoe we've created so far. It's faster. It's more flexible. It's ready to push limits. This lightweight trainer is ideal for all high-intensity workouts, both indoors and outdoors. Its unique slip-in bootie construction allows for an extremely secure fit, and its responsive footbed technology provides the perfect underline to every workout: resilience and support. We've updated this version with a knit upper for a distinctive, modern look.
