“The best socks I have ever tried!! They come in such fun designs, I love the ethos of the brand, and they're the only socks that actually stop me from getting blisters. Slowly replacing all my socks with Sums... ;)”

“So smooth! They are the best running socks I’ve ever used - I’ve tried many pairs over the years. I love how you can barely feel them once they’re on even though they have a nice compression to them. I also love their exchange policy where you can send a pic of you recycling your previous running gear and they give you a free pair! More initiatives like that would be great as waste from clothing is a nightmare to the planet.”

“Brilliant socks! Comfy, breathable and no blisters or hot spots. They’re come in a nice length so don’t sit too high or low on the shin. Nothing worse than long socks. Love the styles.”

“I have used SUMS socks previously and have returned to purchase another 3 pairs, the company do offer a fantastic deal if you send old pairs back, they will send you a new pair in your next order. The socks are great, I compete in ultra runs and rate these socks.”

“Found sizing to be a little out. Quite tight fitting. Too expensive for a pair that I will probably not use in future and choose alternatives.”
