INTELLIGENT BACKBONE SHANK FUNCTIONAL SYSTEM/INSOLE, IN PARTICULAR FOR POINTE BALLET SHOES (INTELLIGENT VERTEBRAL INSOLE - BACKBONE SHANK)

摘要

The invention relates to the "backbone shank functional system" which is a pure molding composite of basic components that are functional and can be produced efficiently. The complete system replaces the conventional insole of the pointe shoe. The backbone shank functional system guarantees long durability, combined with the permanent possibility of easily re-optimizing the flexural behavior and the flexural characteristics of a ballet pointe shoe again and again under changing conditions and demands.
