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.
