Lightweight EVA foam cushioning, mesh upper, flexible outsole

Back in the 1980s, Reebok briefly overtook Nike as the top athletic shoe brand. They did it by creating a shoe made specifically for a new exercise craze: step aerobics. (They made the plastic step too. Smart.) Nike countered by creating a brand new category of footwear: the cross trainer. That marketing game is still being played today. What's popular? HIIT or high intensity interval training. So why not make a shoe just for it? That's exactly what Reebok did with the HIIT TR. It's a grippy, versatile shoe designed to support whatever style of jumping around you like to do to make your heart beat fast.
