Runner's socks and underwear

Why a technical sock

A cotton sock absorbs sweat and holds it against the skin: the foot softens, rubs, and blisters appear. A running sock made of synthetic fibres or merino, like the Sums or Lorpen Ultra Run, wicks moisture away, and its anatomical heel and toe, often differentiated for the left and right foot, fit the foot without creasing. Flat seams at the toes prevent chafing.

Toe, double layer or thick

Toe socks from Injinji, available in Lightweight, Midweight or Original Weight thicknesses, isolate each toe and eliminate blisters between them, which are common on long distances. Double layer socks, like those from Vertical, have the two layers rubbing against each other rather than the skin. The thickness is chosen based on the shoe: a thin sock in a snug shoe, thicker on trails for cushioning.

Compression and recovery

Compression socks, like the CEP Reflective, the Injinji Over the Calf or the BV Sport, exert greater pressure at the ankle that decreases towards the calf. This graduated compression supports the muscle, limits vibrations with each impact and promotes venous return, both during exercise and in the hours following a long run. Size is chosen based on the measurement around the calf and ankle. Socks should be washed at 30 degrees, inside out, without fabric softener.

Frequently asked questions

How can I prevent blisters when running?

Wear technical socks made of synthetic fibres or merino, which wick moisture away, in the right size to avoid creases. Anatomically designed heel and toe models, like the Sums or Lorpen Ultra Run, fit the foot without rubbing.

What are toe socks for?

Toe socks, like those from Injinji, slide each toe into its own sheath: they prevent rubbing between toes and blisters over long distances. They require a few outings to get used to.

Are compression socks useful for running?

They support the calf and limit muscle vibrations with each stride, which reduces fatigue during long runs. Worn after exercise, they promote venous return and recovery.

What size of running socks should I choose?

Take the size that corresponds to your shoe size: too large, and the sock creases under the foot and causes blisters; too small, it compresses the toes. For compression socks, also measure around the calf to determine the size.

How do I wash technical socks?

At thirty or forty degrees, turned inside out, without fabric softener that clogs the fibres and reduces moisture wicking. Air dry them: the tumble dryer wears out elastane and reduces the support of compression socks.
