Great socks…. I have several pairs they are super comfortable and showing no signs of wear. You don’t know you have them on. I would certainly recommend.

I'm a UK size 4 or 4.5 for some brands, so I got the Small sock which fits up to a 7, but I must say it wasn't all that easy to slip them on! I'd also be keen to know how they hold up after multiple washes (as socks are items you can't get away without washing to reduce wear and tear).

I've got plenty of pairs of SUMS for my usual running, but my feet were starting to get a bit chilly so I grabbed a pair of the merino wool. Not disappointed, feet felt cosy over my long run without getting sweaty. Essential part of my winter kit!

Bought as a present for my husband who is currently training for a long distance fell race. He’s very happy with them! Thank you.

The best - feel the socks give my feet extra strength and know I won’t get blisters. Love my new ‘weightless’ hat - stylish and very practical

I didn’t realise that good socks were going to make such a difference to my running… these are incredible! My feet feel secure but not crushed, supported and fresh for every mile! I’m a huge fan, and will be buying more!

10/10! First run with the socks was a 12 mile run on the Cornish coast path which was mainly hills, puddles and rough terrain and didn’t get one blister. I’ll be buying a new pair soon!

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 🤗
