Hilly Mens Twin Skin Socklet Anti-Blister Sports Running Socks for jogging, trail running and sport in general. These newly improved socklets feature double layer construction to absorb friction with breathable, fast wicking fabrics to quickly remove perspiration. The inner layer is made from a knitted super soft feel, durable nylon which is a special fabric called Meryl Sport which has anti bacteria properties plus a beautiful soft cotton like feel similar to Tactel. The outer layer is a blended fabric including Lycra Sport elastane for stretch and recovery, plus some nylon, polyester and cotton for durability and comfort. These socks dry 25% more quickly than the old version and will keep your feet dry and blister free for long distance runs including marathons and ultra distance events. Another improvement is that the upper foot part of the inner socklet is now also vented as well as the outer part and moisture transfer from the inner layer to the outer surface has been improved with the use of fast drying, Dri-Release Cotton. Durability is also better with a higher Nylon content. A higher Lycra Sport content gives a better fit. Total comfort is assured with an improved toe seam.
