Kangoo Jumps are the world's lowest impact shoes. They will reduce the impact on your knees, feet, and back by 40-80%. You wear them like you would any ordinary trainer, but with so much less shock to your system, you should have increased endurance, as well as protection against stress injuries. And if you're running at the gym, you'll get more stares than the triathlon-winning showoff in Nike Shox.
Available online at the Kangoo Jumps Shop.
