The best socks ever. I tried everything to stop blisters during marathons… tape, plasters, double socks. You name it, I tried it. But these socks are the only thing that works! Have several pairs and am never going back :)

Love these sock. Ran a marathon in them and no blisters. Very comfortable and kept feet dry from sweat (was a particularly warm day) Only have 2 pairs so will be buying a couple more now I have fully tested them out.

I do try (well used to!) a new running sock & had many different pairs from many different makers. But… slowly, and very surely, all my them are being replaced by Sums.

Did my first ever Marathon last week in Manchester, dodgy ankles and prone to blisters but Sums was there to save the day. Medium compression supporting my ankles aswell as the materials in the socks preventing my feet from blisters. Best pair of socks ive ever purchased for running and I highly recommend them!

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.
