A shoe extension for gait modification includes a vamp section, a base section, an attachment strap, and a restraining mechanism. The vamp section is connected to a top surface of the base section forming a receiving slot. A toe box of a shoe worn on a healthy limb is slidably positioned into the receiving slot such that the base section is positioned along an outsole of the shoe. The attachment strap is utilized to establish a connection with the shoe. By increasing an overall length of the footwear worn on the healthy limb, a speed of motion of the healthy limb may be reduced in order to increase weight bearing on the unhealthy limb. The restraining mechanism, which is preferably integrated into a bottom surface of the base section, may also be used to reduce the speed of motion of the healthy limb.
