    摘要: A plastic snowshoe having a longitudinal blade with an upturned blunt leading edge. The blade is arched from side-to-side with the concave side down to provide a ground-bearing surface. A downwardly extending ''''skeg'''' is positioned within the concavity of the blade to inhibit rearward slippage of the blade while still allowing forward gliding movement. A longitudinal ridge or keel extends along the center underside of the snowshoe blade to improve the structural rigidity of the blade while at the same time preventing ''''ankle roll''''. A conventional binding or foot stirrup is mounted on a horizontal portion of the upper surface of the snowshoe blade. In the preferred embodiment, a removable, friction-fitted transversely extending ''''centerboard'''' is provided to inhibit rearward slippage on extremely steep slopes.
