Abstract
The invention relates to a sports shoe with an outer shell of injection molded plastic, comprising a front foot shell for accommodating the front foot and an adjoining shoe cuff for stabilizing the lower leg portion of a user, and with a relatively flexible inner shoe at least partially accommodated in the shell. Disposed in the outer shell is at least one elastically flexible portion which is provided as a means of reducing pressure points from the inner shoe on a user's foot when subjected to compression stress. The elastically flexible portion is provided in the form of at least one membrane element which is designed to vary the volume or width which the shell can accommodate as a function of compression stress due to its slackness or ability to deflect relative to the surrounding part-portions of the shell.
