I was recommended these socks by a friend and they have not disappointed. They feel really nice on my feet whether it be a short or a long run. Very supportive material, a nice anmount of compression and nice to look at too!

Love running in these socks, we’re all in the wash when I went on a run and wore a normal pair of branded socks and gave me a blisters after two runs in shoes I always run in.

Superb - used them in the wet soggy trails in West and Mid Wales for trail running. Even when wet - my feet have been warm, whilst grit and trail debris seems to be absorbed and prevented from aggravating the foot. A long pair next 🤗

I bought a few pairs of Sums socks as Christmas presents for runners in my family. They all love them and wear them whenever they run! Wonderful socks for great value.

I have a 4 or 5 pairs of the all seasons but when buying a gift for a family member thought I would try the merino socks. They’re excellent. I have a trail run in Dartmoor this weekend and they have been packed for the race.

I’ve left a review before, but as long as Sums keeps pumping out improved products, I’ll keep leaving 5 star reviews. I run exclusively in Sums All Seasons socks - got em in every colour. Comfortable, blister free, fit great. And they’ve even put L and R on the white ones now, so you always get them on the correct foot :) Hard recommend.

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.
