Title:
WADING CRAMPON
Document Type and Number:
WIPO Patent Application WO/2013/009862
Kind Code:
A3
Abstract:
A non-cleated, soft metal traction device (100) reduces or eliminates slippage on wet and hard surfaces, such as mossy rocks (306) beneath the water surface of a body of water. The traction device (100) includes at least one external metal shank (102,104), plate (206,208) or bar (112) attachable to a footwear item (202) with a desired binding system. The shank (102,104) is preferably made from a soft metal material, such as a non-heat- treated aluminum alloy, so it is soft enough to grip and elastically conform to moist, wet or otherwise slippery rock and shale. The contact surface (224,226) of the shank (206,208) may include grooves, ribs, spaced apart ridges, or other small surface variations to improve the traction of the device in transition environments.
