The 1000 Mile Tactel Race mens running socks not only give you a soft & cushioned feel, but also offer Heel Power technology to hold your feet firmly in place for an enhanced grip & no slippage even at faster speeds. Moisture is quickly moved away from the feet due to Tactel® inner layer that keeps you cool & fresh, whereas top vents provide great breathability & temperature regulation for added comfort. For a more supportive fit, the socks have an arch brace & they are machine washable at 30°C.
