The HIIT XT Mid is made to function like a cross trainer, but ready to take on the city. The upper is a soft custom knit design, while the midsole and outsole are supportive and durable so you are ready to tackle every aspect of your daily life from a gym workout to a shopping trip or dinner date. The removable insole and PowerSole™ technology are a bonus for those days in the gym when you want to be a little closer to the ground for stability and comfort.
