Benefits of technology

[0005]A negative heel exercise device, such as a shoe or an exercise sandal, positioning the heel of the foot lower than the ball of the foot in U.S. Pat. No. D577,882, which issued Oct. 7, 2008 to the inventor of the present invention, may be made of a copolymer of ethylene and vinyl acetate, such as EVA. Herein, a negative heel exercise device means a shoe or a sandal positioning the heel of the foot lower than the ball of the foot. An insert of a gel material or softer elastic material may be embedded or adhered to the surface of the copolymer of ethylene and vinyl acetate, such that the heel of the foot and the ball of the foot are both supported on the insert. While EVA provides a sturdy sole, the insert helps to absorb shock and to reduce slippage of the heel and the ball of th

Problems solved by technology
