Cushioned Sole with Air Chamber and Resistance Protrusions
A shoe providing increased comfort and decreased weight without sacrificing in quality or durability by cresting a chamber below the insole, and preferably in between an outsole and a midsole, with protrusions projecting up from the outsole towards the chamber directly beneath the midsole. In some embodiments, the protrusions may project directly into the chamber but maintains a gap between the top of the protrusions and the midsole.
1 . A shoe, comprising:
a. an outsole;
b. a midsole positioned above the outsole, wherein the midsole is feed to the outsole;
c. a chamber in between the outsole and the midsole, wherein the chamber extends from a front portion of the shoe to a heel portion of the shoe;
d. a plurality of protrusions projecting up from the outsole into the chamber directly beneath the midsole, wherein the protrusions are characterized by a rounded top portion and a base opposite the top portion, the base integrally formed with the outsole, wherein the top portion of each protrusion and the midsole define a gap therebetween when in a natural state; and
e. an arch support within the chamber in between the front portion and the heel portion, wherein the arch support is a rigid sheet having a convex top surface and a concave bottom surface.
2 . The shoe of claim 1 , wherein the air chamber comprises a heel chamber section and a metatarsal chamber section.
3 . The shoe of claim 2 , wherein the heel chamber section and the metatarsal chamber section are sealed from each other.
4 . The shoe of claim 1 , wherein the air chamber 108 , 110 is lined with an airtight lining.
5 . A shoe, comprising:
a. an outsole;
b. a midsole positioned above the outsole;
c. an insole positioned above the midsole;
d. a chamber below the insole, wherein the chamber extends from a front portion of the shoe to a heel portion of the shoe; and
e. a plurality of protrusions projecting up towards the insole, wherein the protrusions are characterized by a rounded top portion and a base opposite the top portion, the base formed adjacent the outsole, wherein the top portion of each protrusion and the insole define a gap therebetween when in a natural state.
6 . The shoe of claim 5 , wherein the chamber comprises a heel chamber and a metatarsal chamber.
7 . The shoe of claim 6 , wherein the two air chambers are sealed from each other.
8 . The shoe of claim 5 , wherein the air chamber is lined with an airtight lining.
9 . The shoe of claim 5 , wherein the midsole is a sealed bladder having a top side and a bottom side with the air chamber defined by the top and bottom side of the midsole.
10 . The shoe of claim 9 , wherein the protrusions are Integrally formed with the outsole and abut the bottom side of the midsole.
11 . The shoe of claim 5 , further comprising an arch support in between the front portion and the heel portion, wherein the arch support is a rigid sheet having a convex top surface and a concave bottom surface.
12 . The shoe of claim 5 , wherein the protrusions are integrally formed with the outsole and protrude into the chamber beneath the midsole, wherein the top portion of each protrusion and the midsole define the gap.
