发明名称 Shoe protector
摘要 A shoe protector for carpet installers and others whose shoe toes are subject to abrasion and chemical abuse. The protector cup includes a pair of superior stabilizers connected to the top of the protector cup and a pair of inferior stabilizers connected to the bottom of the protector cup. A superior and inferior stabilizer are each connected to a stabilizer ring which is in turn connected to a heel strap linking the two stabilizer rings. The stabilizer rings translate the rearward force of the heel strap into pulling forces on the superior and inferior stabilizers in order to allow the protector cup to be pulled not only rearward against the toe of the shoe, but also downward against the shoe toe top and upward against the shoe toe bottom for maximum gripping effect on the shoe.
