Wow wow wow! Have always used another brand for 15 years…..loved the vibe of their socials and saw a lot of the elite UTMB runners wear them and thought let’s give them a blast. OMG!!!!…..Took them for a 22 miler on the South Downs……my feet were bone dry at the end, super cool and zero hotspots. Now have 3 pairs as the first pair I washed and put in the dryer….Don’t do this as they need to be dried naturally so now my mediums are Small size BUT win win as my wife’s has snatched them away as fit her feet perfect. Love them big time. They looks the NUTZ!! So so cool and hip.

Loving these socks. Yes, they are 'only' socks. But they feel great and look great...what more could you want? Oh, a brand that is trying to make some small difference in the world as well? Yes - that too✅ If only they could help me go faster. I think that is all down to me.

First time wearing Sums I took the risk of using them for my first half marathon. Full disclosure I did put compeeds on where I had previously got blisters but other than this the socks saw me through with no blisters anywhere else, there was a perfect amount of compression and I was genuinely very impressed. Really lovely designs too.

Nice fitting socks (I am a 7.5/8) and went for the small and they were fine. Wore straight out of the box for a mountain race without issue (I did have decent plasters on my achilles) and they went through alsorts on the day including bogs and marsh land and were run in wet through. They have washed well, no holes or frays/pulls although I can no longer get them back to white. A little pricey yes, however they delivered what I needed therefore I would say that is good value.

High quality socks, soft but strong. The recycling offer and earn per run perks are good too. Would buy again. Thanks!

I really like these socks. This was my first experience of Sums; the socks are stylish, arrived promptly and super comfortable. I also really like the incentive to gain discount on further purchases by getting out and logging runs (connected via Strava) as often as possible! I will be ordering again! 5-stars!
