Abstract

See full text

Footwear with a heel portion having a clasp member with resilient arms having locking tabs that engage with locking slots in a receptacle member in a main portion, when the heel portion abuts against the main portion. The locking tabs disengage from the locking slots when simultaneously squeezed together by a tool that extends through locking tab access holes on both sides of the main portion. The locking tab access holes are too small for a child's fingers to enter. The clasp member and receptacle member can be in either the heel portion or the main portion.
