Ordered 2 x pair of SUMS running socks due my Nike's biting the dust after 200km. I ordered a large and when they turned up I intiially rhough they felt quite small, however, after getting them on they were very comfortable and the extra compression really paid dividend. So far I've only completed about 40km with one pair, and about 10k with the other but so far I'm very impressed in the comfort, and how they create zero hot spots or uneven pressure points. Something I found happened frequently with my Nikes.

Very good comfortable hq socks. Used for about 25km so far mix of on and off road. Find they are a little short on my lanky legs and tend to slip down to end up even smaller. But I’ve never had a pair of running socks that don’t do this!

Feel good straight out of the box. Excellent fit, super fast wicking and ice cool designs make Sums some of the best socks out there.

My go to socks! They've got me through a 53 mile ultra marathon, zero blisters. They stay in place, they're comfy, and they do them in my fave colour (lilac). Great customer service too!

Since running in SUMS I’ve felt so much more comfortable. No movement, no discomfort after long runs and seem to really wick sweat well….and dry quick too. Look cool too. Big fan.

Extremely comfortable socks, almost a compression sock yet feel so soft. I can't see myself buying any other socks, I've worn Darn Tough, More Mile, Injinji, CompressSport and SUMS beat them all for comfort, keeping feet cool and no hot spots.

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.
