Perfectly fine on icy surfaces.

Studded shoes make winter walks safer. The cushioning in the Shelter Spikes shoes is optimized for walking. Carbide studs installed in the forefoot and heel areas provide grip on ice and hard-packed snow.
Note: Do not rely blindly on the stud’s grip – if the ice is very uneven or covered with snow, the studs may not provide effective grip.
Note: Studs can damage many flooring materials and may be slippery on stone floors or metal surfaces at doorways. Do not use the shoes indoors!
