If you wear large trainers then the chances are you’ll need to wear large running socks. But whatever size you take, it’s important to choose the right ones. A badly fitting sock can do as much damage to your feet as a badly fitting shoe.

Although it’s true that just about any sock will offer some protection and comfort, only a sock specific to running made out of the latest fibres will provide sufficient protection and comfort while also controlling the flow of moisture off the foot.

The hotter it is and the harder you run, the more you sweat as this is the way your body cools itself. A lot of the sweat ends up in your socks so a wicking sock is very important. Wicking means it moves moisture from your feet to the outside of the shoe. A technical running sock made of breathable yarns can do this because it doesn’t hold on to the moisture generated in the feet by running. If your feet stay dry, it will help to avoid the friction between your feet and shoes which can lead to blisters.

Another key factor when choosing running socks is the fit. Certain socks will fit certain feet very well, while others will not. A correctly fitting sock will reduce the friction from unruly seams, fabric gathering and baggy fit. All of these can increase the risk of calluses, blisters and black toenails.
