The socks are very tight, I bought a pair for myself and one as a gift for my husband - my pair super tight on the ankles, left a huge indentation and very uncomfortable. My husband cannot wear his pair - all round too tight. Will be sticking with the Injini toe socks,

I chose sums because I ran a 42km training run and ended up with a blister on the arch of my foot at 10km in. I have never been a believer in sock choice although I thought why not , let’s give these so called anti blister socks a shot. And fair play since then(knock on wood ) no issues up to 30km at the moment . So well done. And I would highly recommend

Socks way too small for me. Advertised as size 9 - 11 but I can barely squeeze them on. And cost a lot of money too. Very, very disappointing indeed.

My absolute favourite running socks, I wish I’d switched to sums much sooner!

I have spina bifida occulta which has caused chronic root nerve damage in my lower back, leading to muscle deterioration in one leg. I find wearing a compression sleeve really helpful, and combining that with Sums socks has made a noticeable difference in day to day life. The socks provide supportive, even compression without feeling restrictive, which helps reduce pain and fatigue throughout the day. They are comfortable to wear for long periods, stay in place, and give me added support and confidence when moving about. They have become an essential part of how I manage my symptoms on a daily basis.

Socks are brilliant! Comfortable and wear well plus like the designs I do struggle with the colours and layout of the website for me not user friendly 😁

We bought these socks for our son and he absolutely loves them. At last a pair of socks designed for running and work! Definitely recommend these socks for runners and walkers!

Really happy with these socks. The fit is great. Super comfortable and they stay in place the whole run. The secure fit really stands out. This makes such a difference on long runs.

Great quality socks. Perfect fit. Also just every purchases the Marino wool brown socks and they are brilliant while out on a cold/ wet trail run. Keeps the temperature perfect.
