“Great quality product! And love the option to recycle your old running socks for a free pair with purchase. Great incentive to come back again and again.”
“Extremely pleased with these socks. They work perfectly with my walking boots. My next test will be wearing them with my doc martens. Very happy customer and have already repurchased a couple more pairs.”
“Sum's socks are super nice! Very beautiful designs and great aesthetics - a great change from other running socks. They are good at moisture wicking, and stay in place, and no blisters at all. I'm training for a half marathon, and I'm using these for all my training sessions so far. I am wearing them with Hoka trainers and I find them quite hot inside the shoes, but I think this is more about the shoe than the sock. Would reccomend”
“Wore these socks for the Belfast Marathon 2025 (yesterday) not having tested them beforehand may have been a bit risky but it paid off, very comfortable and no blisters wouldn’t have a negative thing to say about and will for sure be buying another pair in the future!”
“Brought a few pairs for my longer runs. Comfortable, with light grip to avoid slipping and so far so good. Zero blisters or rubbing. Would recommend.”
“On the Ascenders - Excellent socks. Last weekend a friend and I did our final recce of the Ultra Trail Snowdonia 50 route ahead of the actual race on May 17. After 38km and two ascents of Snowdon I had no blisters or hotspots. Great product, well worth the money. (photo included as proof of a genuine review)”
“Great socks, but even better customer service. I ordered the wrong size, the team were able to respond to my request and replace them in less than 24hours. Thank you!”
