When I purchased SUMS sock I was pulled in my the social media targeting and bought 3 pairs of these as they looked pretty cool. But now having received them I can confirm as well as looking fantastic, they are also incredibly comfortable and my new go to for all my runs. I’ve already recommended them to friends and will be buying more colours! Fantastic product and the website is very different, love it.

Been using sums for a few years now. Have about 8 pairs. The first pair of socks I bought in 2022 I still wear. A great quality product & they look good

Excellent supportive socks that really help make your foot and heel/ ankle area feel strong. Breath well and are my favourite socks for all my trail running except perhaps ultra distances where I would opt for toe socks for added risk of blistering between my toes rubbing together when wet or damp - perhaps Sums do them already ? If not I’d suggest they do please ?

Great sock designs, durable, comfortable and really help my feet during my long runs. Ran 100-130km cumulatively in my 5 pairs and all still work fantastically.

I was really excited to get these socks & gave them a baptism of fire wearing them for my first marathon. I am unbelievably impressed with them, particularly the compression and support. They take great care of my feet & are miles better than any other brand I've tried. Also the colours are fab!

I always trained in Nike Drift socks and never had any problems, but when I switched to new shoes and did a long run, I started getting rubbing on my feet. I wasn’t sure if it was just the shoes, but I didn’t want to risk blisters. I came across Sums socks online and decided to try them—bought three pairs. I even wore a fresh pair straight out of the pack for my Half Marathon at LLHM 2026. Honestly, they were great. No blisters, no rubbing at all. Definitely my go-to socks now for both training and races.

The best socks I have ever tried!! They come in such fun designs, I love the ethos of the brand, and they're the only socks that actually stop me from getting blisters. Slowly replacing all my socks with Sums... ;)
