This was a Christmas present for my grandson who wears them all the time whilst running. He was very pleased to receive them.

Bought as a Christmas gift for my dad after we had both spotted adverts online, Hr couldn’t be more chuffed. The colours are great and strong and the quality is lovely. Definitely will be returning

Been using/ordering Sums for almost two years, they’re a staple for any kind of run - from Parkruns to ultra marathons. Super comfortable, best looking sock out there and with a lot of sock types. Some of the first socks I ordered varied in how well they fitted (M were very tight) but that’s certainly not a problem more recently. I haven’t looked it up but if you don’t offer a repair service that might be a good idea, especially for damage to limited pairs like the black/orange Mavericks. Albion does a very good service. But as you can tell, Sums are great and I’ll continue to use them for every run. Keep up the good work!

THE best running socks, I won't wear anything else! Comfy, non-slip, they still look fab after long use, beaut colours and design! Never had blisters or anything, even when running a marathon. Honestly, they're ideal running socks and worth every penny. I also love that they recycle old running socks!!

The Merino Blend sock is an absolute banger. I struggled to find the perfect sock for me, but these tick all of the boxes! Will certainly be back to try some different offerings from SUMS. The socks are erring on the more expensive side, but longevity has been wonderful thus far and I'm sure I'll get many more miles out of them.

If you want to put your best foot forward, these are the socks you need! Having suffered with blisters on long races and tries many other brands that haven't lived up to the task, finally I've found the solution to blister clear feet. Sums Ascenders have paved the way for perfect pinkies.

These are the best socks I’ve ever had for trail running, every other brand I’ve used have meant that I’ve had to use various different methods to prevent blisters but the Tom Evans sucks from Sums have been so comfortable and blister free over long distances and challenging terrain. They are incredibly comfortable, even when wet and seem to dry really quickly rather that retain water when I’ve run through significant rain.
