Patent number: 9161593Abstract: A heel traction aid (HTA) includes a gripping pad and a traction device having an upper surface, where the gripping pad includes a receiving bore penetrating the gripping pad and a raised ring encircling the receiving bore. The traction device is disposed in receiving bore such that the upper surface is disposed below the raised ring. The HTA includes a heel cup attached to lateral edges of the gripping pad, a first strap attached to the heel cup and including a first hook, and a second strap attached to the heel cup and including first holes. The first and second straps have elasticity sufficient to maintain tension when a heel of a shoe or foot is positioned in a concavity formed by the gripping pad and the contoured heel cup and when the first hook is engaged with one of the first holes of the second strap.Type: GrantFiled: August 17, 2011Date of Patent: October 20, 2015Assignee: Sure Foot CorporationInventors: Jon C.

Patent number: RE42965Abstract: An overshoe that is removably disposable on a user's shoe and provides a tread surface that enhances the user's footing on slippery surfaces. The tread surface has removable spikes that penetrate surfaces and forward-oriented and rearwards-oriented gripping ridges that grip the surface. The ease of pulling on and removing the overshoe is enhanced by using stretch zones that are placed to allow stretching of the overshoe to fit over a shoe or the like without compromising the snugness of the overshoe fit. A spike assembly for use with an overshoe that fits over a person's shoe and enhances a person's contact with the ground, includes a spike having a head operably coupled to a shank; and a button overmolded on the spike and having a neck for removable engagement in a bore defined in the overshoe. A method of minimizing slippage on a ground surface is further included.Type: GrantFiled: December 5, 2006Date of Patent: November 29, 2011Assignee: Sure Foot CorporationInventors: Jon C.
