The compression and cushioning has upped my running experience for sure. Great colours, tough and arrived quickly in low-impact packaging. Thank-you!

The best socks in the game bar none! Wore a new pair on the weekend for an 18 mile run and there were absolutely zero hot spots, blisters or any level of discomfort. Can’t recommend them highly enough

Arrived very quickly. Great quality. I ran 2O miles in them the day after getting them. No hot spots or rubbing. Very comfortable Will be using them on ultras this year and I will feed back again afterwards.

Lovely socks. I had a problem with the size (I ordered too small) but Sums were more than happy to arrange an exchange, which they did very quickly. Great customer service

Love these socks! Got bought a pair for Christmas and I used them for the rest of my cross country season. They have now become my staple go-to sock, and I will be using a pair to get me over the Edinburgh half marathon finish line in May. Thankyou 🙂

Overall really pleased with these socks. I followed sizing guide advice and purchased a size medium for my UK9 feet. I was initially worried that they were too small but once tried on they fit perfectly...snug but not tight or restrictive. No hotspots so far and comfortable after several hours in the wet. Highly recommended and ill be back for more.

Great quality socks and very comfortable for running. I initially had some trouble getting a response from customer support when trying to arrange a return/exchange, which took a couple of weeks and several emails. However, once the team saw my review they got in touch quickly, apologised for the delay, and resolved the issue in a very generous way by letting me keep the original pair and sending another pair out. Really appreciate them putting it right, happy to support a small brand that stands behind their product.
