Compression Socks Explained
In brief: Compression socks are close-fitting socks that apply graduated pressure to the lower leg, tightest at the ankle and easing further up the calf. Runners wear them during long runs to support the muscles and after running to aid the feeling of recovery and reduce leg swelling. They are a simple, reusable piece of kit popular for both performance and recovery, though benefits vary between individuals.
What are compression socks?
Compression socks are snug-fitting socks, usually reaching to just below the knee, knitted to apply a controlled squeeze to the lower leg. The pressure is graduated, meaning it is firmest around the ankle and gradually eases higher up the calf. They come in different compression strengths and are made from stretchy technical fabrics designed to stay in place.
How they work
The graduated pressure is intended to support the veins and muscles of the lower leg and to encourage blood flow back up towards the heart. During running this is thought to help support the calf muscles and reduce muscle movement, and after running the gentle squeeze may help reduce swelling and the feeling of heavy, tired legs. Responses vary, and some runners feel a clear benefit while others notice little difference.
Why runners use them
Runners wear compression socks both while running, particularly on long runs, and as recovery wear afterwards or even overnight. The appeal during running is support and a secure feel for the calf, while the recovery appeal is reduced leg swelling and a fresher feeling in the legs the next day. They are also popular for travel after races, when long periods of sitting can leave legs feeling heavy.
How to use them
Choose a size based on calf measurement and shoe size so the fit is snug but not painfully tight, and pull them up smoothly so the pressure is even with no bunching. They can be worn during a run, afterwards for a few hours, or overnight for recovery. If they feel uncomfortably tight, leave marks that do not fade, or cause numbness, they are too tight and a different size or strength is needed.
