Due North Qwik Grip Mid-Sole may generally help give you traction on ice, snow or other porous surfaces that you may encounter on a day-to-day basis. No product can completely prevent a slip or fall on unsafe surfaces that may be slippery, greasy or unstable. This Qwik Grip Mid-Sole may only help with traction if worn on proper footwear that has a 90 degree defined heel and if placed properly as shown on the user guide. The Due North Qwik Grip Mid-Sole only provides traction for the user if the users foot is firmly placed on the surface during stepping in a flat position. Do not wear with high heels, slippers or any other type of shoe that does not have a solid bottom or top. Qwik Grip Mid-Sole aids are not meant to be worn on slick surfaces such as granite or marble or on ladders or similar equipment or when driving a vehicle. Use care as Qwik Grip Mid-Soles are sharp and may injure or damage flooring, surfaces or skin.
