amorriso (Canada) Sports sweatpants to help you run faster It would be important to anchor the sweatpants in place so they don't ride up or down as you run. You could anchor them below by making them fit over the foot like a stocking and anchor them above with suspenders. You also wouldn't want to make the elastic too stiff or the person couldn't bend their legs properly. If you could just store maybe 40% of the energy when they hit the ground in the elastic it should be enough to make it significantly easier for them to push off the ground for the next stride.
