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 šŸ‘

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!

Unreal socks. One of my favourite brands, managed to snag a limited edition hat from Love Trails a couple of years ago which is now my prized possession. Don’t tumble dry!!! 🄲

Best trail running socks I've ever had. Perfect fit, function, comfort, durability. I've tried socks from every leading (and many a niche) maker of trail running shoes and apparel. And years of trial and error with brand after brand keeps leading me back to Sums as the champion.

The perfect running socks. They keep my feet blister free, they look good, and wash really well. I've bought many pairs for friends and family 10/10

Be been trying to find a sock that will be durable and keep blisters at bay. Recently started using some new shoes and they have been giving me blisters so the week before a race I was worried about these shoes ruining my feet….decided to give sums a go and they were brilliant!! I didn’t need any plasters on my feet just other socks on and had no issues for the first time in a long time so I’m happy!
