Sometimes a little grip goes a long way, which is why Yaktrax’s original Walk ice-traction system has withstood the test of time. The unobtrusive design slips on to shoes to add greater traction across slippery surfaces. Whether heading to school, work or the end of the driveway, the Walk helps make every journey a little safer. Mens sizing. XS is up to 4.5. S is 5-8.5. M is 9-11. L is 11.5-13.5.
