Abstract: A tactile feedback shoe sole for footwear comprising a main body that defines a toe portion, a middle portion and a heel portion. A first chamber filled with a fluid is disposed in one or more areas of the main body. A second chamber comprising a second chamber upper wall, a second chamber lower wall and projections is disposed in the arch region of the middle portion. Channels disposed between the first and the second chambers help in establishing fluidic communication between the first and second chambers. If the second chamber is compressed before the first chamber getting compressed, which is likely to happen when the feet of the user of the sole overpronate, the second chamber upper wall comes in contact with the second chamber lower wall and the projections are felt by the user in the arch region since the second chamber is not filled with the fluid.

Abstract: A tactile feedback shoe sole for footwear comprising a main body that defines a toe portion, an arch portion and a heel portion. A first chamber filled with a fluid is disposed in the toe portion. A second chamber comprising a second chamber upper wall, a second chamber lower wall and projections is disposed in the heel portion. A channel is disposed at the arch portion between the first chamber and the second chamber. If the first chamber is pressurized first before exerting pressure on the second chamber, which is likely to happen when the user of the sole runs following a forefoot running technique, the fluid from the first chamber flows to the second chamber and the fluid in the second chamber does not allow contact of the heel of the user to come in contact of the projections present in the inflated second chamber.
