I decided to get a pair of sums after reading about them in ultra running. I’m a fussy sock connoisseur and I must say I’m not disappointed. The material feels quality and must importantly they fit and feel great when running.

The socks are excellent and perform very well on long runs. However, I was slightly disappointed to find that although I ordered two pairs in the same size, one pair is noticeably smaller than the other. Both labels indicate the same size, so this inconsistency was unexpected.

Ran the Epona 100 in these, took spare socks but didn't need to change into them, no blisters or hot spots, reassuringly supportive and breathable, superb.

I’ve had a fair few pairs from Sums now and they have held up very well. Many 100kms and never had issues.

I've worn the socks quite a lot on my trip to Japan, I'm doing 20K+ steps a day and they are really comfy and I haven't had any blisters at all

Sums are the best socks I have run in. No blisters, no movement. Customer service is also top notch.

Ran a half marathon days after receiving a pair of the ‘All Seasons’ socks, in a new pair of trainers, no blisters or even hot spots at all. Very comfortable and well fitted. Highly recommend.

Amazing socks!! Run in them all the time and I’m sad when I can’t wear them because they are being washed. Very good quality and very comfortable. Even the style makes them stand out in a crowd.

Great running socks. Super! But I hadn’t checked the import duty in Italy charges, but that’s my own fault.

Tried the thicker / more cushioned version this time around and really like them - comfortable and great for longer runs!

The socks are really good. Compression feels nice but not too tight like some other running socks. Used them on longer runs and my legs felt much better after. Comfortable and easy to run in for a long time.
