Love these socks! As soon as I put them on, they were lovely and supportive and compressive - I knew I’d have a great comfortable run!

Have had several pairs of Sums now and they are a super sock. Really comfortable, durable and my feet love them on long runs and shorter sessions.

I ran a half-marathon in Sums having only a few tested them out on one run pre-race (I know I know never do anything new on race day). My socks were great, my feet didn’t blister at all and they definitely did their job!

Ran my first ultramarathon this weekend. After 53km and 6,500ft of elevation, not one blister! Couldn't ask for much more than that really.

Love them. The material and fit feels great on your feet and the grips underneath mean they don’t move around in your shoes. Put them on, run, enjoy.

I was a bit sceptical at first due to the pricing but bit the bullet and put these to the test and I must say I absolutely love these! I’ll never look back now as the quality of these socks is second to none. Good incentives and savings for future purchases - will definitely be buying more !

Great socks, but after few runs they already feel "used" where the shoe rubs on them at the front. Glad I got a few pairs!

Used a pair of the Tom Evans collab for CCC & they did the job perfectly, no blisters, no discomfort. Top level socks

I bought 3 pairs after seeing the ads on instagram as I like the fact that they donate to charity and recycle old socks. The socks themselves are great; comfortable, breathable and padded whilst not being too thick. I’ve used them over a variety of distances, up to about 15k so far, and not any issues with blisters or overheating and my feet have been dry at the end of my runs. I struggled slightly getting the first pair on as they are quite snug (even in the largest size) but once they’re on they’re not too tight, they’re comfortable and supportive. Will buy more when the time comes. Hopefully there will be some new colour ways as well at some point.

Great socks. Didn’t realise the difference having specific running socks would make. No friction, movement, blisters from using the SUMS socks. Really pleased with the purchase and would highly recommend to anyone thinking about purchasing a pair.

I tried numerous running socks before and always got blisters until a friend put me on to SUMS and I’ve never looked back. Hands down best running socks I’ve ever worn, never had a blister since.

If people could see me they would presumably say something like “wow, that runner’s socks are so cool and, by virtue, have made that runners whole aesthetic and personality cooler!!!” ……… however, the socks have made me run so much faster that I have become just a blur as I pass said people. The socks are great!

Who would have thought socks could improve your performance as much as SUMS socks do.!!
