I recently ordered some Sums for the third time and really like the latest socks. The first pair, which are thick cotton ones and very comfortable, have ripped at the quarter seam by the ankle. The second pair have become almost impossible to put on as the fabric has become so tight, but the third pair are top drawer. Elasticated, mid-shin and comfortable, not to say really stylish. Well played, Sums!

I picked up my first pair of Sums from the running show at the NEC Birmingham and I haven't ran in a different sock since then, I am now 6 pairs deep and have even bought them as birthday and Christmas gift since, sums have been in my trainers throughout the training block and during my first marathon this year, blisters? What blisters?

I have worn sums socks here there and everywhere, local runs to running and scrambling up Snowdon twice. Very comfortable and a fit and forget item! Love them.

Seem good so far, worn a handful of times, felt a bit slippery the first wear but better after a wash

Best running socks, use for fast races and finished a summer 100k ultra with feet in great condition, and they still look new after a wash. Have 10 pairs now.

Amazing quality, supportive, very wicking, good compression. Will be buying a few more pairs.

Used my new All Seasons on both Man v Horse and Swansea Ironman, they were great. Comfortable and importantly they didn’t move about on my foot unlike other brands. Will order more and recommend to my triathlon / running mates!

I own five or six pairs of Sums socks at this point and the number will keep growing. When I’m doing anything more physically demanding than a walk, I pop them on and know my feet will be alright. I just left the Yorkshire Three Peaks blister-free and I know it’s down to Sums. If you’re on the fence, I encourage you to give it a go — you genuinely won’t be disappointed.

These guys are double rad. I haven't worn any other sock since switching to Sums. I'm thinking about not running on trails anymore so I can keep them fresh for longer.

Great socks, loved them so much I went and bought a second pair. I was having trouble with leg pain since wearing the Sums socks this pain has gone! Thanks!

Very good socks. Used in a 100 mile ultramarathon in the wet and the socks held up very well indeed.

After trying various brands of trail running socks, I got a pair of Sums, they are without doubt the best trail socks I have used. Did a 47km race with wet feet for the last third without any hot spots or blisters. 10 out of 10 from me.
