Great on first wear but are a lot smaller after the first wash - despite washing at 30 degrees. I'm size 10 and would get the size large (11-13) in hindsight

Great socks, wouldn’t train in anything else. No blisters or irritations, keep the feet nice and cool on long distances.

Great, durable socks. I have 3 pairs now and wouldn't ever need to think about buying another brand. Cool designs and very comfortable. Have ran 1x marathon and 1x half marathon in them plus 30km+ weekly.

Sums socks are great! They are light and breathable but also padded in the right spots to keep me blister free.

Love your socks! After wearing stance for years I tried sums as really like your ethos and designs. My sport is fell running and my footwear takes a lot of battering in all weathers... sums socks haven't rubbed once. They are the perfect thickness and wash without shrinking. Great product 👌🏼 Im based in the lake district and happy to trial any new stuff 😉

I’ve been looking for some comfortable socks for ages to use at the gym. These fit very well & are very very comfortable. I highly recommend them.

Great socks, great concept. Orders come with a pre-paid label to return old socks and get a free pair with your next order!

I live my sims socks but they don’t stop the blisters as much as I had hoped! Especially on my little toes. But generally they feel secure, look cool and I will probably buy more.
