These socks look great and feel great. High quality, provide good cushion and are true to size!

Can't rate them highly enough, the Ronseal of socks. They do exactly what they say on the tin. Used them for my first 50 mile ultra and not 1 blister.

Training for a marathon & out of all the socks I’ve tried (about 7 different ones) Sums have been the best by far!

I’ve seen these for a while on Instagram and always thought they looked good but hesitated, choosing cheaper socks. After doing more running and finding socks that weren’t always up to the job I decided to try SUMS out. I am not disappointed. they are stylish and very comfy. As a bonus I am getting money off my next purchase every time I run!

I have over 10 pairs of Sums now. Wouldn’t use any other brand for my running socks. Perfect fit on every pair and have never had any issues with slippage or degrading of quality. Would recommend every time.

So far no complaints. Really comfortable running socks. They've also shown no signs of wear and tear. I've got 6 in rotation and won't be using anything else.

From a (soon to be) 1st time London marathon runner, inexperienced but training hard before the big day, blister free thanks to these fantastic socks!

Have been wanting to try for awhile but price point was stopping me. Then listening to That’s Runnable and how Tommy expresses how good they are. Then following tom Evans and hearing the development through him. Made me buy 4 pairs. Absolutely loving them and will be wearing them on most of my runs.

Good quality. Look great. Really comfy. Wore them the day they arrived on an 18k run. Felt great. Will wear them on an upcoming half marathon.

These socks are amazing. I ran a 20 mile mountain trail event in them. Running through streams and muddy fields and my feet stayed blister free. The socks dry off really quickly so you don't have the problem of wet feet for hours on end. I liked them so much I bought another couple of pairs for myself and sent some to my son.
