Sneakers that Put a Spring in Your Step (Literally!)

Could a tiny coil hiding in the heels of these sneaks make you run like the wind? These Spira sneakers might have metal springs built inside the heel, but they're a far cry from the Moon Shoes of our childhood. These springs in these kicks wont send you flying into zero gravity, but they do boast an 87% return in energy. That means that for every step you take; the springs absorb and return 87% of your effort, cinching recovery time. The springs also reduce 20 percent of the impact on your body every time you slip them on so you can say goodbye to aches and hello to the open road.

SELF intern Motahareh says: I love the idea of shoes that will make my morning jog easier and possibly make me faster! I've had the Paseo Trail Runners for a couple months now and I've found that I'm exceptionally more active, on and off the track. Now, could my new job in the fitness department also have caused this? You bet. But I also know that these sneaks are a lot more lightweight and comfortable than anything else I've bought in past two years, and that, I can definitely live with!
