“First pair of Sums. Used for some local trail runs and during a 6 day Dales Way hike. No issues during either activity. No hot spots, blisters, very comfortable and supportive. Will be buying some more.”
“Really comfortable socks . I’m a size 10 uk and bought medium as per guide and fit fine . They don’t bunch up . Great colour ways to choose from and arrived quickly .”
“These are the only running socks I will use..
Comfy, I don’t get blisters and they are hard wearing..
My old pair is still going strong but bought three more pairs..”
“They arrived super quick after ordering them and I managed to wear them for the Glasgow Half Marathon. Really comfortable socks, no blisters or hot points. Best socks I’ve bought 😃”
“Wore these sock for the first time last Sunday for a 15 mile run. I found them really comfortable with no blisters. I am now -planning to wear them for my marathon in 3 weeks time. Probably the best running socks I have tried. I have already recommended them to my running friends.”
“Hello hello , I am using sums sox every run I do .My last time I run ,was at cardif half marathon 2025 and I wore white long once and I have to say ,they were great .Little bit to long as I am not that tall hahahahah .I have so many now ,that you guys need to come up with more colours xxxx”
“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.”
