Lovely socks! I’m a UK size 8 and would recommend going for size Small in them.

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 πŸ™‚

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.

Very good so far, have been comfortable and durable. Very breathable on the foot too hardly notice them which is always a good thing.

Very pleased with my new socks, on a super wet and cold London Winter run I had no issues with my feet, socks performed very well! And looked pretty fetching too😁

Lovely look and feel, good quality socks. Scored down as they are incredibly tight. Ordered size 8-10 (for size 10 feet) and were so tight restricted blood flow and were not comfortable to wear for long run.

Absolutely brilliant socks. Have a few pairs of theses and on a 100 mile race I only changed them once. No blisters and no rubbing. They kept my feet in good condition even though I had been through bogs and wet land over the course of the 100 miler. Even when moving uphill they did not move once. Can not recommend these socks enough.

These are my third pair of socks and I really enjoy them when out. I don’t have any problems or blisters during any long run.

My son and grandson love these socks. They are both cross country, half marathon, marathon and Ironman heroes. They haven't found anything else to compare these socks to. Great achievement πŸ‘

Fantastic socks! Worn for a few long runs now and no blisters or pain. Before this I was getting blisters on many of my long runs so these have been an absolute game changer!
