ABSTRACT:
A training shoe can apply a larger-than-normal load to leg muscles to strengthen them while maintaining good flexibility, cushioning properties and other necessary properties required for shoes. Regularly arranged weight chambers are formed in a resilient outsole. Weights formed of a mixture of metallic grains and an adhesive are embedded in the weight chambers. A rubber layer is provided between the outsole and a middle sole, and a thick cup-shaped insole is laid on the middle sole to absorb shocks. Also, a fairly thick tongue is provided to protect the instep of a foot.
