He also has invented a new heel for boots and shoes, which is molded of hard india rubber, and making the same hollow, to receive a filling piece of india rubber sponge, or other elastic and yielding substance, which projects somewhat beyond the edge of the enclosing case, so as to form a cushion or buffer for easing the blow of the heel when it strikes upon the ground.
