ABSTRACT:
The climbing shoe is covered with thin, flexible, high-friction rubberlike material on the outside of the shoe from the area of contact of the ball of the foot forward to the toe all the way up to the midline of the shoe. This comprises an engagement surface so that the shoe can be turned and the toe inserted into a crevice with the engagement surface against one wall of the crevice to enhance traction and protect the shoe upper.
