The Hilly Twin Skin anklet has fantastic moisture management capabilities and anti-blister properties. It features an anatomical design with abrasion resistance in areas of increased wear and additional ventilation in key areas for improved breathability. The double sock construction absorbs friction, whilst the Meryl® Skinlife inner sock wicks moisture to the outer cotton sock, keeping the skin dry and you, more comfortable. It also features soft-touch reinforced heel and toe areas and an arch grip heel for an improved fit. The VentFlex panelling on the front of the ankle also helps to improve performance by helping keep your feet cool and comfortable in key areas. HILLY was founded by Dr. Ron Hill MBE, BSc, PhD. The first man to break 2h 10mins in the marathon, Gold Medal Marathon Winner, a man with a PhD in Textiles Technology, and someone who hasn't missed a days running training in 45 Years! If anyone knows how to make ideal socks for your feet, it's this man.
