Abstract
It consists of a device that is achieved by giving a special configuration, reproducible in molds, to the two pieces that form the sole. These will be constructed of elastic material and we will call them conventionally. Both are designed to fit perfectly and their fit is airtight. Between both is a gap that is the breech of air. It communicates with the sole of the foot by the numerous holes that the plant carries and with the outside by three or four valved side holes, in one or both sides of the shoe, located at the beginning and in the upper part of the heel, perforating the piece that we call it sole. The pressures and decompressions of the chamber are made in the simple action of walking by elasticity of their materials. (Machine-translation by Google Translate, not legally binding)
