I bought the little yellow running socks - very cute and comfy - no blisters on my long runs, looking forward to trying some others!!

I bought these for my son. He says they are brilliant - apparently the sign of a good sock is that you can’t tell you’re wearing them when running - we’ll be buying more!

These are the BEST running socks I have ever owned. A friend of mine recommended SUMS, so I thought I’d give them a go and ordered a pair. After wearing them a few times, I ordered one for every day of the week and now wear nothing but SUMS for my gym workouts and running! Oh, and I’ve just bought the running cap. LOVE.

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
