Recently upped my weekly milage and was starting to get issues with current socks rubbing on insole of left foot. Bought some Sums socks. First test was an 18km run and they were fantastic. Run every time in them since. Really good sock. I will be buying more.

Second purchase of a few pairs of the checkers design socks. Really pleased with the comfort, fit and performance of Sums. Ran 19 miles over the fells on Thursday and 20 on Sunday. No issues. The the toe box area could be improved either way a more toe shaped fit and the medium compression could be tighter.

Snug fit, love the grips, comfy plush trail socks. Take a while to dry out if you get your feet wet/ compromise I guess with cushioning. Proper quality socks though.

Love these running socks! Super comfy, breathable, and the compression feels amazing—keeps my feet supported and fresh. No blisters, just happy miles!

Love these - ran a 10 mile trail run in them at the weekend and had zero issues. They’re super snug fit and lovely material. I’m always sceptical about socks when they say they’re anti blister but these have been great.

Thought I had an issue with one of my socks but George at SUMS took the time and care to check and explain the new tech. Really helpful and fantastic customer service! Also I have to say I’ve stopped buying other brands for running socks since SUMS, they are simply the best out there and backed by great service too.

I have worn my new Suns socks twice this week , the first time was on Tuesday ( a track session) & the 2nd time was on Thursday for a 10 miler. They are very comfortable to wear, & look cool. I’m looking forward to wearing them on the 27th when I run London

They say don't try new things on race day but I broke that rule and ran the London Landmarks half with Sums socks on. Not one blister or rubbing. Fantastic!
