Novelty: an increased-stability shoe sole for comfortable walking is disclosed. Constitution: the main body of whatever material, colour, shape and size, the sole composed of two or more layers (5,6,7) of whatever material, shape, colour and size, and a special layer placed transversely or under angle at the underside of the sole 6; the construction material of the foregoing special layer is harder than that of the other layers (5,7) while the NBR sole protrusions can independently move from the rest of the sole when pronation troubles or problems due to soil surface irregularities are manifested. Retreated into the more flexible layers of the sole or into their projections found at the underside of the sole, the aforementioned NBR protrusions balance the manifested troubles and give the sensation of comfortable walking shoes. |
