Good looking, good supporting running socks that also make a great gift.

A lighter weight feel but I havent had any issues with blisters yet from either trail or road running.

These are the perfect mix of comfort and support. I've never thought about having running specific socks before as I don't run that much but I'm definitely ordering more now.

Amazing fit, so comfy and really washes well. Nothing like my usual brand which get smaller with each wash.

Best running socks I have had! Super comfy, good fit and the right thickness. Also the colour choice and pattern a bit funky which is nice.

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

Fantastic socks. No rub or friction. Stayed in place the whole run.

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.
