Tested and proven by world class Olympic athletes from around the globe, we have invested two years in perfecting the PULSE. The PULSE features linked toe construction on a 168 needle machine and is crafted for the skin tight environment of your track spikes, or the highly formed cycling shoe, ski boots and skates – The PULSE is the low volume sock of choice for speed. There is no compression sock thinner than the PULSE. The PULSE breathes, helps you avoid blisters and features our new and exclusive micro silver bonding.
