Extremities socks have been leading the world in high tech materials and construction for nearly 20 years. Our ‘Toesters’ have been proved time and time again on expeditions from the North Pole to the summit of Everest and provide the basis from which the rest if the range are designed. We have been using Merino Wool in our socks from their very inception as well as incorporating various different knit densities to provide the most accurate fit.

As the range developed the ‘Toester’ became the ‘MountainToester’ and the famous ‘Thinny’ and ‘Thicky’ socks arrived. Now, over two decades later, the Extremities sock range is larger than ever and still at the forefront of product design. The current range includes a sock for almost every application from adventure racing to mountaineering. Our socks have covered mile after mile as part of our sponsorship of the Britvic Marathon of Britain and a multitude of high altitude expeditions. All to ensure you can forget about your own feet and enjoy your own expedition, however near or far.

Using innovative fabrics, such as Wool Ultra™ and Coolmax™ our socks provide the better recovery from compression, less friction to reduce blisters as well as excellent moisture management and warmth. Combined with our fantastic fit these properties add up to the most comfortable environment feet and they will thank you for it at the end of the day.

We saw far less blistering than in previous years and more competitors made it to the finish line.’
Rory Coleman, Britvic Marathon of Britain Race Director

‘Changing to Extremities sock was the best move I could have made. For 8 more days and 8 more marathons my feet started to heal rather than worsen.
No blistering, no hot spots and lots more comfort. My search for a fantastic sock is over.’
Daniel Brockhurst, who ran 25 marathons in 25 days

‘I got no blisters until I wore my Thorlo’s on Wednesday; when I got about 4.’
