Abstract

Footwear including a sole for supporting a foot and an upper attached to the sole for covering the foot. The sole and upper define an interior of the footwear sized and shaped for receiving the foot. The upper has an inner surface adapted for engaging the foot when it is received in the interior of the footwear and an outer surface forming an exterior of the footwear. The upper also includes compressible cushioning permitting the upper to conform to the foot when it is received in the interior of the footwear to improve the fit of the footwear. The compressible cushioning is sized, shaped and positioned in the upper to at least partially surround a protrusion extending from the foot and is at least partially omitted from an area of the upper corresponding to the protrusion. Thus, a recess is formed in the upper for accommodating the protrusion to relieve pressure applied to the foot by the upper at the protrusion. The protrusions which are thus accommodated include protrusions at the heads of the first and fifth metatarsals, a portion of the fifth toe corresponding to the fifth proximal phalanx, and portions of the ankle corresponding to the distal heads of the tibia and fibula.

Claims

1. Footwear comprising a sole for supporting a foot and an upper attached to the sole for covering the foot, said sole and upper defining an interior of the footwear sized and shaped for receiving the foot, said upper having an inner surface adapted for engaging the foot when it is received in the interior of the footwear, an outer surface forming an exterior of the footwear, and compressible cushioning positioned between said inner surface and said outer surface, said cushioning permitting the upper to conform to the foot when it is received in the interior of the footwear to improve the fit of the footwear, said compressible cushioning being sized, shaped and positioned in the upper to at least partially surround a protrusion extending from the foot at a head of a metatarsal of the foot and being at least partially omitted from an area of the upper corresponding to said protrusion of the foot thereby forming a recess in the upper for accommodating said protrusion to relieve pressure applied to the foot by the upper at said protrusion.

2. Footwear as set forth in claim 1 wherein said compressible cushioning is sized, shaped and positioned in the upper to at least partially surround the protrusion extending from the foot at a distal head of a first metatarsal of the foot, and is at least partially omitted from the area of the upper corresponding to said protrusion of the foot thereby forming the recess in the upper for accommodating said protrusion to relieve pressure applied to the foot by the upper at said protrusion.

3. Footwear as set forth in claim 2 wherein said protrusion is a first protrusion, said recess is a first recess, and said compressible cushioning is sized, shaped and positioned in the upper to at least partially surround a second protrusion extending from the foot at a distal head of a fifth metatarsal of the foot, and is at least partially omitted from an area of the upper corresponding to said second protrusion of the foot thereby forming a second recess in the upper for accommodating said second protrusion to relieve pressure applied to the foot by the upper at said second protrusion.

4. Footwear as set forth in claim 3 wherein said compressible cushioning is sized, shaped and positioned in the upper to at least partially surround a portion of a fifth toe of the foot corresponding to at least a portion of a fifth proximal phalanx of the foot, and is at least partially omitted from an area of the upper corresponding to said portion of the fifth toe so said second recess in the upper further accommodates said portion of the fifth toe to relieve pressure applied to the foot by the upper at said toe.

5. Footwear as set forth in claim 2 wherein said compressible cushioning is sized, shaped and positioned in the upper to at least partially surround a portion of a fifth toe of the foot corresponding to at least a portion of a fifth proximal phalanx of the foot, and is at least partially omitted from an area of the upper corresponding to said portion of the fifth toe thereby forming a second recess in the upper for accommodating said portion of the fifth toe to relieve pressure applied to the foot by the upper at said toe.

6. Footwear as set forth in claim 1 wherein said compressible cushioning is sized, shaped and positioned in the upper to at least partially surround the protrusion extending from the foot at the distal head of a fifth metatarsal of the foot, and is at least partially omitted from the area of the upper corresponding to said protrusion of the foot thereby forming the recess in the upper for accommodating said protrusion to relieve pressure applied to the foot by the upper at said protrusion.

7. Footwear as set forth in claim 6 wherein said compressible cushioning is sized, shaped and positioned in the upper to at least partially surround a portion of a fifth toe of the foot corresponding to at least a portion of a fifth proximal phalanx of the foot, and is at least partially omitted from an area of the upper corresponding to said portion of the fifth toe so the recess in the upper further accommodates said portion of the fifth toe to relieve pressure applied to the foot by the upper at said toe.

8. Footwear comprising a sole for supporting a foot and an upper attached to the sole for covering the foot, said upper having an inner surface adapted for engaging the foot when it is received in an interior of the footwear sized and shaped for receiving the foot, an outer surface forming an exterior of the footwear, and compressible cushioning positioned between said inner surface and said outer surface, said cushioning being formed from a first material having a first compressibility selected for cushioning corresponding areas of the foot, and a second material having a second compressibility greater than said first compressibility selected for accommodating corresponding areas of the foot, said first material being sized, shaped and positioned on the upper for at least partially surrounding a protrusion extending from the foot at a distal head of a metatarsal of the foot when the foot is in the interior of the footwear, and said second material being sized, shaped and positioned on an area of the upper corresponding to the protrusion so that the upper applies less pressure to the protrusion than to portions of the foot surrounding the protrusion.

9. Footwear as set forth in claim 8 wherein said first material is sized, shaped and positioned on the upper for at least partially surrounding a protrusion extending from the foot at a distal head of a first metatarsal of the foot when the foot is in the interior of the footwear, and said second material is sized, shaped and positioned on an area of the upper corresponding to the protrusion.

10. Footwear as set forth in claim 9 wherein said protrusion is a first protrusion, and said first material is sized, shaped and positioned on the upper for at least partially surrounding a second protrusion extending from the foot at a distal head of a fifth metatarsal of the foot when the foot is in the interior of the footwear, and said second material is sized, shaped and positioned on an area of the upper corresponding to said second protrusion.

11. Footwear as set forth in claim 10 wherein said first material is sized, shaped and positioned in the upper to at least partially surround a portion of a fifth toe of the foot corresponding to at least a portion of a fifth proximal phalanx of the foot when the foot is in the interior of the footwear, and said second material is sized, shaped and positioned on an area of the upper corresponding to said portion of the fifth toe.
