A sports shoe, preferably for tennis includes a rigid stirrup member with a pair of first portions that extend downwardly and rearwardly, on opposite sides of the shoe, to the sole, and a second portion that extends around the back of the shoe and is connected between the first portions. The first portion on the inside part of the shoe extends over the navicular bone, and the second portion extends behind the calcaneous bone of the foot. When the first portions are fastened together, the stirrup member encapsulates the calcaneous, navicular, and talus bones to provide medio-lateral support to critical stress-bearing bones and joints.
