Abstract
A climbing shoe includes an inner sole, an outer sole and a molded middle sole between the inner sole and the outer sole. The middle sole is concave in shape. The outer sole conforms to the concave shape of the middle sole. The concave shape allows the outer sole to hook on a rocky ledge. The molded middle sole provides a structure that causes the concave outer sole to substantially maintain the concave shape when pressure is applied to the outer sole.
