The socks have been great to run in but they are very very tight & it has taken some getting used to.

Great socks, very comfortable. These are second set purchased as first were great and built to last. No blisters after several half marathons.

Used SUMs socks for the Springtide 50km Ultra and to be fair I didn’t think about my feet at all, they were great. No blisters and stayed comfortable the whole way through. Would definitely recommend.

Saw Sums advertised on Instagram and thought they'd be a gimmick but the adverts came up a few more times and having often struggled with my feet whilst running i took the chance, instant game changer, complete comfort whilst running, they don't slip, the designs are great, 10/10 socks for the athlete (or portly lad) in your life

First time out over 30km. No hotspots. No blisters. No drama. Brilliant socks. I highly recommend the all seasons to anyone who loves running and even more so to those that don’t! Game changer.

Adore these socks. I wear them for everything from the weekly 5km to regular ultra marathons. They fit snug to the mid foot but allow for toes to splay whilst running which means they don’t feel restrictive at all. My favourite socks are the All Seasons and the max cushioned.

Brilliant! I love my Sums! I often get blisters but haven’t got one yet while wearing my Sums. I’ve bought them for my husband and sister-in-law who also rave about them. Loving the new colours available. Will definitely be getting more xx

The best socks for me so far, I've struggled with blisters for any type of longish run, untill I got these. Did my first half marathon (Cambridge) in march and NO blisters, absolute bliss. Highly recommend, I ordered more straight away

After trying multiple different brands of running socks and not really having much a good time with any of them, i jumped in and tried Sums. This is it, these are the socks your looking for. The best ive worn.

I have tried so many socks, these are a dream. Training for a marathon and have put in lots of miles and not a blister in sight. This is the first pair of socks that I have worn that have actually prevented blisters. I love them.

The only sock I will ever run in is a pair made by Sums.

Heard good things about the socks so ordered 3 pairs online. Not sure what I was expecting, but when they arrived I thought, “hmmm, what’s so great about these. Shouldn’t they be like, thicker 😂”. Shows how little I knew! The socks are great. They fit is so snug you forget your wearing them. And as for my initial concern about their “lack of thickness”, I wore them regularly whilst prepping for a recent half marathon and didn’t blister once….Great product. Highly recommend.
