Abstract

Footwear comprising a sole for supporting a foot and an upper attached to the sole for covering the foot and adjoining ankle. The sole and upper define an interior of the footwear and is sized and shaped for receiving the foot and ankle. The upper has an outer shell that forms an exterior of the footwear and an inner lining that is adjacent the foot and ankle when they are received in the interior of the footwear. A compressible generally U-shaped pad is positioned between the shell and the lining of the upper. The pad has a bottom section and a pair spaced-apart side sections extending up from the bottom section. The pad is sized and positioned in the upper such that when the foot and ankle are received in the footwear, the bottom section of the pad is disposed immediately below a medial malleolus of the foot and the side sections of the pad extend up along opposite sides of the medial malleolus up to at least about the distal neck of the tibia. Upon movement of the foot and ankle in the footwear, the pad is adapted to apply an intermittent pressing force to tissue of the ankle below and on opposite sides of the medial malleolus to reduce swelling of the ankle. A U-shaped pad for the opposite (lateral) side of the ankle may also be provided.

Claims

1. Footwear comprising

a sole for supporting a foot,

an upper attached to the sole for covering the foot and adjoining ankle, said sole and upper defining an interior of the footwear sized and shaped for receiving the foot and ankle,

said upper having an outer shell forming an exterior of the footwear, an inner lining adjacent the foot and ankle when they are received in the interior of the footwear, and a compressible generally U-shaped pad positioned between the shell and the lining of the upper, said pad having a bottom section and a pair spaced-apart side sections extending up from the bottom section, said pad being sized and positioned in the upper such that when the foot and ankle are received in the footwear the bottom section of the pad is disposed immediately below a medial malleolus of the foot and the side sections of the pad extend along opposite sides of the medial malleolus up to at least about a distal neck of the tibia whereby upon movement of the foot and ankle in the footwear the pad is adapted to apply an intermittent pressing force to tissue of the ankle below and at opposite sides of said medial malleolus to reduce swelling of the ankle, and

inside tiller material between the shell and lining and between the side sections of the pad, said pad having a hardness and resistance to compression greater than that of said inside filler material.

2. Footwear as set forth in claim 1 wherein the spacing between said side sections of the pad generally corresponds to the width of the lower end of the medial malleolus.

3. Footwear as set forth in claim 1 wherein the bottom section of the pad is curved to conform to the lower end of the medial malleolus.

4. Footwear as set forth in claim 1 wherein said inside filler material has a hardness at least 10 durometer units on the Shore C scale less than the hardness of said pad.

5. Footwear as set forth in claim 1 wherein said pad has a Shore C durometer in the range of 25–

70.

6. Footwear as set forth in claim 1 wherein said pad is an integral part of the footwear.

7. Footwear comprising

a sole for supporting a foot,

an upper attached to the sole for covering the foot and adjoining ankle, said sole and upper defining an interior of the footwear sized and shaped for receiving the foot and ankle,

said upper having an outer shell forming an exterior of the footwear, an inner lining adjacent the foot and ankle when they are received in the interior of the footwear, and first and second compressible generally u-shaped pads positioned between the shell and the lining of the upper, each of said first and second pads having a bottom section and a pair spaced-apart side sections extending up from the bottom section, said first and second pads being sized and positioned in the upper such that when the foot and ankle are received in the footwear the bottom section of the first pad is disposed immediately below a medial malleolus of the foot and the side sections of the first pad extend along opposite sides of the medial malleolus up to at least about a distal neck of the tibia, and the bottom section of the second pad is disposed immediately below a lateral malleolus of the foot and the side sections of the second pad extend along opposite sides of the lateral malleolus up to at least about a distal neck of the fibula, whereby upon movement of the foot and ankle in the footwear the first pad is adapted to apply an intermittent pressing force to tissue of the ankle below and at opposite sides of said medial malleolus and the second pad is adapted to apply an intermittent pressing force to tissue of the ankle below and at opposite sides of said lateral malleolus to reduce swelling of the ankle, and

inside filler material between the shell and lining and between side sections of the first and second pads, said pads having a hardness and resistance to compression greater than that of said inside filler material.

8. Footwear as set forth in claim 7 wherein the spacing between said side sections of the first and second pads generally correspond to the width of the lower end of the medial malleolus and to the width of the lower end of the lateral malleolus, respectively.

9. Footwear as set forth in claim 7 wherein the bottom sections of the first and second pads are curved to conform to the lower end of the medial malleolus and to the lower end of the lateral malleolus, respectively.

10. Footwear as set forth in claim 7 wherein said inside filler material between the side sections of each pad has a hardness at least 10 durometer units on the Shore C scale less than that of said pad.

11. Footwear as set forth in claim 10 wherein said pad has a Shore C durometer in the range of 25–

70.

12. Footwear as set forth in claim 7 wherein said first and second pads are integral parts of the footwear.
