Anti-slip stocking sole
A compression stocking is described with anti-slip means at the bottom surface of the stocking sole. The anti-slip means comprises one or more elongate grip members having a wave shape. The sole comprises a fabric tread and at least a portion of the elongate grip members overlies the tread.
1. A compression stocking comprising:
a foot portion for covering at least portion of a wearer's foot, the foot portion including a toe region and a heel region and a sole extending between the toe region and heel region, the sole having a woven or knitted bottom surface for contacting a floor; and
anti-slip means provided at the bottom surface of the sole, the anti-slip means comprising:
a plurality of polymeric elongate inner grip members, each inner grip member having a wave shape and each inner grip member overlaying at least a portion of the woven or knitted bottom surface; and
a polymeric elongate outer grip member, the outer grip member comprising a continuous U-shaped polymeric strip of material that partially surrounds the plurality of inner grip members, wherein the opening of the U-shape is adjacent the toe region.
2. The compression stocking of claim 1 , wherein the wave shape is a substantially sinusoidal shape.
3. The compression stocking of claim 1 , wherein the wave shape is a substantially zigzag shape.
4. The compression stocking of claim 1 , wherein the bottom surface of the sole extends between the toe region and heel region in a longitudinal direction of the sole and an elongation direction of the inner grip members having the wave shape are substantially in a lateral direction of the sole, perpendicular to a longitudinal direction.
5. The compression stocking of claim 4 , wherein the inner grip members are spaced apart in the longitudinal direction of the sole.
6. The compression stocking claim 1 , wherein the anti-slip means extends substantially the whole length of the sole between the toe region and heel region.
7. The compression stocking of claim 1 comprising a toe opening surrounded by a welt.
8. The compression stocking of claim 7 , wherein at least a portion of one of the inner grip members is provided at a distance of no more than 2 cm from the welt.
9. The compression stocking claim 1 , wherein the bottom surface comprises a tread.
10. The compression stocking of claim 9 , wherein the tread provides the bottom surface of the sole with a rougher surface than surrounding surfaces of at least one of the foot portion and the bottom surface, and the anti-slip means overlays at least a portion of the woven or knitted tread.
11. The compression stocking of claim 1 , wherein material of the stocking, forming at least the sole of the stocking, is antibacterially treated.
12. The compression stocking of claim 1 , wherein the anti-slip means are elongate and have a width of less than 5 mm.
13. The compression stocking of claim 1 , wherein the anti-slip means comprise silicone.
