Shoe with exchangeable additional soles, skates, etc. connected to conventional sole via studs and spring-loaded struts locking into apertures

摘要

The shoe has a conventional sole (2) containing one or more fastener mechanisms, which lock with corresponding rigid head studs (4) in the additional sole. The connection is locked or released by the mechanism. Instead of the additional sole, the shoe may be connected to a walking aid, rollers, skis, skates, etc. The studs lock into apertures (8) in the sole, which extend into its interior. A coiled metal strut (5) is moved by a spring (7) and blocks or permits the stud movement into the aperture.
