The perfect sofa buddies for a Friends marathon, or for wearing with boots for a winter walk out to your favourite Central Perk-style coffee shop, these SOCKSHOP Heat Holders 1.6 TOG Lite Friends Thermal Socks feature an array of motifs instantly recognisable to any fans of the sit-com TV classic.Made to keep your feet warm and comfortable without the bulk of standard Heat Holders, these Lite socks still manage to achieve a cosy 1.60 TOG rating for their thermal efficiency, but at a thickness which can be easily worn with everyday casual shoes and boots. Specially developed advanced Japanese-designed thermal yarn is knitted into a medium-length looped pile cushioning inside the socks, which has then been intensely brushed into fleecy, soft and silky fibres that are designed to trap warm air within them, keeping it close to the skin for hours of insulated warmth. These Heat Holders are constructed with gentle non-binding tops that protect circulation, making them diabetic-friendly.
