In a range of colours and patterns, designed as a medium thick, mid-weight sock for casual shoes and boots, when regular Heat Holders socks are just too chunky for your footwear, then these Heat Holders 1.6 TOG Lite Patterned and Striped Socks will fit the bill... and in your shoes! They’re made from the same thermally efficient, Japanese-designed yarn as the full thickness socks, but with less dense bulk and shorter loops to the pile lining.

The looped pile of every sock is then intensively brushed, giving the surface not only superb softness, but a bed of fleece fibres that can trap more warm air, holding it in those fibres and close to the skin, which allows the socks to keep your feet warmer for longer, proven to be more than 4x the warmth of a basic cotton sock. For your even closer-fitting shoes, perhaps try our minimum thickness SOCKSHOP Heat Holders 1.0 TOG Ultra Lite Plain Socks.

About Heat Holders

Since then, we've used our world-leading insulation knowledge to create ranges of thermal underwear, tights, hats, gloves, neck warmers and more. We also now offer a range of products to bring more warmth right into your home, including our toasty thermal blankets, which are available in a wide range of colours.

Whether you want a warm pair of socks to do the gardening in, for walking the dogs, skiing down the slopes or just padding about the house in – this is the range for you.

TOG (Thermal Over Grade) is an independent laboratory tested standard. The higher the TOG rating, the better the product is at keeping you warm!

We have Ultra Lite 1.0 tog which is 3x warmer than regular cotton socks. Ultra Lite 1.6 which are 4x warmer than regular cotton socks! This makes our lighter TOG socks perfect for slipping into boots for walking.

We also have our Original 2.3 which are perfect for those chilly nights at home as they are 7x warmer than regular cotton socks!

* our TOG rating results are based on testing a sample cotton sock and a sample Heat Holders , according to British Standard 4745 two plate method for thermal tog rating.
