PROBLEM TO BE SOLVED: To provide sports shoes with an outer shell of injection molded plastic.SOLUTION: These sports shoes have a front foot shell 4 which holds a foot region and an adjoining shoe cuff 5 which stabilizes the lower part of a leg of a user. An inner shoe 3 which is relatively flexible is held at least partially in a shell 2. In an outer shell 2, when receiving compressive stress, at least one elastically flexible portion 10 prepared as a means to reduce a pressure point produced on the foot of the user by the inner shoe 3 is arranged at a predetermined position. The elastically flexible portion 10 has at least one membrane element 11 which is prepared so that it changes a considering volume or width, which can hold the shell 2, as a function of the compressive stress due to its slackness or ability to deflect relative to the surrounding part-portions of the shell 2. |
