Yaktrax Spikes place seven points of contact under the ball and heel of your foot that provide significant traction on all icy surfaces. The durable tungsten carbide spikes are permanently housed in molded rubber lugs that are shaped to provide additional traction on packed snow. Yaktrax Spikes are lightweight, easy to use and stow, and work well with most types of footwear, making them ideal for navigating icy sidewalks and parking lots in the city. The reflective performance strap ensures a secure fit, and the outer band remains elastic even in subzero temperatures. Imported.
