The most comfortable running sock I've ever had the pleasure of wearing. My Fiance bought me a pair for my birthday at the start of August and within a couple of weeks I'd already bought myself a second pair as my other (non-Sums) running socks don't cut it any more. Plus, they look really cool.

Great experience buying running socks with Sums. The socks are really nice and have not had any blisters wearing them.

Absolute god send! I don’t get blisters on long runs any more, I was pleasantly surprised because the aggressive instagram advertising was a bit of a red flag but they’re actually really good quality and have made running less painful

Loving my new socks! My feet don't get hot and I am not suffering anymore, thoroughly recommend these socks, they worked great on my seven mile run and were recommended to me by a fellow running friend.

Feels great and much batter feels over traditional socks

Thinner than I expected. But so far so good when worn

Never going back! I’ve been wearing Sums for a few years. They’ve been through half marathons, trail runs, CrossFit events and just standard life. The only accurate review of how much I rate them is by how many pairs I now own…

Can’t get enough of these socks. Incredibly comfortable and look so cool as well. Will definitely be repeat ordering.

I love the designs and quality of the socks. But unfortuntely I feel they're sized wrong - I'm UK size 9 and the M really is too small. Sadly only realised after the first run when they only covered the ankle. I would recommend going a size up

The socks are the ONLY ones I’ve ever found to prevent me from getting blisters. I am truly a fan and so is my husband of his. Also Eloise in customer support is an absolute legend who helped me when a pair went rogue in the washing machine and the support was unreal.

I am a recent convert to Sums, having purchased a pair about a month ago. Pleased to report they are the bees knees - without any shadow of doubt, the most comfortable running socks I’ve had the fortune to try.

I originally bought the small size (my true shoe size) but these quickly became much too small and hurt my toes to wear for long periods. I now can’t even get them over my feet. Since sized up and they fit much better however are still on the verge of being uncomfortably tight. Otherwise love them.
