Even in the coldest weather, when chunky boots and footwear are often the order of the day, some of us have times when we need to wear neater, closer fitting shoes but how to keep warm in them? SOCKSHOP Heat Holders 1.0 TOG Ultra Lite Plain Socks are the answer, a fine and smooth looking men's thermal sock with a cosy secret that all regular Heat Holders wearers might guess. Scientifically tested and proven to be over 3x warmer than the basic cotton socks you'd wear with tight-fitting shoes, these Heat Holders Ultra Lite socks use the company's Japanese-designed insulating thermal yarn, knitted with their innovative technology for a loop pile inner that is brushed to produce a plush layer that can maximise the amount of warm air held inside the sock for day-long warmth, even in those tight dress shoes!
