With a very classic boot sock look, knitted in a range of two-colour marl twist yarns, other than a small Heat Holders patch on the leg, you won't see much difference between these ladies' SOCKSHOP Heat Holders 2.9 TOG Merino Wool Socks and other outdoor socks... but you'll definitely feel it when the cold bites hard! Heat Holders achieve a cold- and competition-beating 2.9 TOG rating by bringing together the natural heat retaining and wicking properties of soft merino wool with selected man-made fibres and innovative knitting technology. Densely padded, the longer looped inner pile is intensely brushed for a soft finish that captures and holds heat, as well as cushioning feet for lasting warmth and comfort during all outdoor activities in cold conditions. Reinforcement at the heels and toes is added for extra protection during heavy use. SOCKSHOP Heat Holders Women's 1 Pair 2.9 TOG Merino Wool Socks in Wine Size: 4-8
