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.!!

Been running for about 15+ years and these are best runners I’ve ever run in! Cool colours, nice fit, no/low blistering after long runs. Awesome!

I've never given the socks I run in much thought, bought a few pairs of SUMS because they look sick then omfg, they are so comfortable. I've worn normal socks since, that I had run in before and I can feel such a difference. SUMS fit snug and comfortably close to the foot so they don't slip around at all on me.

Honestly… Sums socks blew my mind this weekend at Tribal Clash in Dartmouth 🙌 I had two pairs – one for Saturday, one for Sunday – and they handled everything. Saturday they went straight in the sea for the first workout, then I continued to wear the same pair for the worm, then onto the bars, running, climbing, you name it. Feet were soaked, sandy, sweaty… but ZERO blisters. Not even a hot spot. Sunday I took them on the 5k trail run (again, wet and muddy) and still came out with happy feet. No soreness. No rubbing. Nothing. Just solid comfort all weekend long. Genuinely didn’t think socks could make such a difference, but these did. Can’t recommend them enough – 100% worth it if you want your feet to survive a weekend like that 👌🧦

The best compression running socks! I had MONSTER blisters from doing a few 10KM+ long runs after wearing ordinary cotton socks, and needed to stay on top of my training, so bought these SUMS socks to see if they’d help - SO glad I did! They’re genuinely the only socks I wear on my runs now. Can’t recommend enough, and they look cool with any leggings or shorts as well. LOVE!

Super comfy socks, not too thin or thick, stayed in place during my run, and no hot spots which I struggle with, will definitely be buying another pair !
