Soft Instep closure system - The rigid polyurethane part has been reduced and coupled to soft, thermo-formed Eva and it is anatomical. The system eliminates the need for the High Instep Extender.
Increased comfort and performance - Red SL buckle Allows locking in two different ways: by taking up a number of clicks with one sweep of the lever, or engaging one half a click at a time for a truly micrometric adjustment. The two red flaps may be pressed together for complete unlocking or alternately to slightly loosen the shoe during performance
Velcro Security System - High security Velcro with integrated locking polymer teeth, that engage onto each other when the strap is closed.This feature makes the closure more secure and the Velcro becomes unmoveable.
