The 1000 Mile Ultimate Tactel ladies socks keep your feet dry & fresh during intense running sessions thanks to a moisture-wicking Tactel® inner layer that moves perspiration away from the skin & feature arch bracing for extra support & a firm fit. To avoid slipping & lock the foot in place, the socks use Heel Power technology & a double layer construction helps to prevent blisters & minimises friction. These durable & breathable socks with top venting guarantee a comfortable temperature for the foot & can be washed in the machine at 30°C.
