Athletic shoe, particularly a soccer shoe, with a springy-elastic sole

Abstract From the Canadian patent

An athletic shoe particularly a soccer shoe, with extreme flexibility in the ball area and, preferably in the mid-foot joint area, as well, is achieved by the provision of ribs in these areas on the contact side of the sole as well as on the insole side. The ribs form a continuous undulating band consisting of wave crests and valleys and may be formed as a unitary part of the sole or may be a separate component made integral with the sole during manufacture thereof such, as by the sole material being injected or case around them.
