I’ve heard a lot about Sums, they live up to the hype. Super comfy and great on the trails. Now my running socks of choice 🔥

The BEST socks. Comfortable, stay up - you basically forget you’ve even got them on. I’ve purchased two more pairs

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..

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.

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!
