INSTALLATION INSTRUCTIONS:
Always check shoe sole depth before installing Grip Studs.® Grip Studs® shoe studs can be installed with the Grip Studs® manual installation tool. Snap a stud into the tip of the install tool (auger end facing outward). Position the end of the stud firmly against a thick knob of the shoe sole. Firmly apply pressure straight down while slowly screwing the stud into the sole until the prongs on the tool penetrate the rubber. Remove the tool from the stud. The notched collar on the stud should be flush with the rubber. Studs may come out if they are not adequately sunk into the rubber. Repeat procedure for all studs. For optimum traction, install studs in varied pattern (not in a straight line) on the sole so the studs can make better contact with the terrain. Grip Studs® are also easily removed by backing them out with the same tool. 
 
CAUTION:
Over-tightening may cause studs to penetrate entirely through shoe soles; verify sole thickness before installing studs.
Studs may damage or mar floors, truck beds and other surfaces
Shoes with Grip Studs should NOT be worn with snowshoes as will damage snowshoes and void warranty.
