Durable and lightweight easy-fit steel spikes for excellent grip on ice and packed snow. The Yaktrax XTR ice grips provide extreme traction on snow and ice, with their high strength steel spikes and corrosion resistant chains. Anti-balling snow plates prevent the spikes getting clogged with snow, and the natural rubber outerband will adapt to most types of footwear and remains flexible in temperatures down to -41 degrees! When not needed the XTR fold up and pack away neatly into the included durable carry bag, sized 15 x 15 x 7cm. For oversized footwear like snowboots it's recommended you go up one size.
