Publication number: 20150342305Abstract: An anti-slip overshoe has a contoured outer band and first gripping pad and second gripping pad disposed interior to the contoured outer band for enhanced traction. A web structure connects the first gripping pad and second gripping pad to the contoured outer band. A plurality of gripping devices is attached to the first gripping pad and second gripping pad for enhanced traction on natural surfaces. The gripping devices includes a body, button extending from a first end of the body, plurality of spikes disposed around a perimeter of the body, and central spike extending from a second end of the body. A neck is disposed around the body between the button and spikes. The spikes include a traction arm, plurality of edges formed along the traction arm, and concave surface between a first edge and second edge along the traction arm.Type: ApplicationFiled: June 1, 2014Publication date: December 3, 2015Applicant: Sure Foot CorporationInventors: Jon C.

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: 7409782Abstract: An anti-slip overshoe includes a contoured outer band, a gripping pad disposed interior to the contoured outer band for providing traction, and a web structure connecting the gripping pad to the contoured outer band. The gripping pad can include gripping ridges for providing traction. The gripping pad can include ridge spaces for providing traction. The gripping pad can include removable grip devices for providing traction. A method of making an ant-slip overshoe includes providing a contoured outer band, providing a gripping pad disposed interior to the contoured outer band, and providing a web structure connecting the gripping pad to the contoured outer band.Type: GrantFiled: February 18, 2005Date of Patent: August 12, 2008Inventors: Jon C.

Patent number: 6442763Abstract: An insulating hood that is suitable for wearing on a person's head. The insulating hood includes a main portion, a resilient portion, an elongated cord, and a pair of lock mechanisms. The main portion has an opening formed therein. The resilient portion is attached to the main portion proximate a lower edge of the opening. The elongated cord at least partially extends through the main portion around the upper edge and side edges of the opening. The pair of lock mechanisms releasably engages the elongated mechanism. Changing the position of the lock mechanisms on the elongated mechanism permits a circumference of the opening to be reduced.Type: GrantFiled: January 10, 2001Date of Patent: September 3, 2002Inventors: 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.
