When I think of gravity the word down usually comes to mind. I definitely do not think of gravity as a way to enhance my running, maybe my falling but definitely not my running. Until now...
The good (and super smart) folks over at Velocy, an innovative company have come up with the notion of Forward Gravity -- Forward Gravity™ Technology is engineered to assist in human locomotion by providing a support chassis at the forefoot that allows it to serve as the primary support and balance system during walking and running. Forward Gravity also reduces braking forces by shifting the emphasis of support from the heel to the forefoot. Thus relieving stress on the heel, ankle, knees, and the rest of the body.
Sounds complicated, I know.
Basically Velocy's Forward Gravity design allows runners to maintain a forward lean, resulting in improved technique which in turn leads to fewer injuries, a more comfortable run and improved performance. The Runner's Shoe (pictured, $125) is available at Velocy.com.
