I wouldn’t wear any other running socks. I ran the Snowdon Marathon at the weekend in what some are describing as the worst weather conditions they have seen. The socks were once again amazing, so so comfortable and stood up massively to the test. Really impressive. 🔥

The socks are essential to my running. I’ve not found a better running accessory.

Amazing socks, communicative on delivery to the US and useful marketing e-mails. I got a few as gifts and they've been VERY well received!

These are my go to socks for everything, but especially big workouts and race day. They fit so comfortably with running shoes and look great too. I wore them for Boston Marathon in Spring this year and after a 2:57 PB, I’d wear them for any other race!

Sums socks were recommended to us by our son in law who's an ultra runner. I purchased 4 pairs for hiking the West Highland Way and they were just perfect for 100 miles on a mild Oct week.

Great socks. New to running and pushing myself to longer distances building up to a marathon and these socks have been great - no blisters whatsoever and a nice level of compression. Cute colourways too

The best running socks ever!! Yes, they are expensive but you pay for what you get. I was gifted a pair of sums socks last year and have since treated myself to an extra few pairs as they are so good! The quality is amazing and they have a good mix of colours / designs. I also love the fact you can buy more and save money, I tend to buy my friends / family who are into running a pair.

These socks are amazing! Blisters on the sole of my foot were a bug issue and if tried other brands and wrapping them in bandages but nothing worked. Since investing in SUMS I haven't had a single blister. They're brilliant!

Great quality sock with superb support. Only a small thing but as they are tight on the skin it can be hard to adjust them when putting on.

Great socks . I've been running for 40 years and I think they are the best I've had. Buy a single pair to try then buy in bulk to save money .
