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.

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.

Great socks! Really comfy. I ran a half marathon and got no blisters and I’m usually prone to them. Highly recommend.

Been on the hunt for decent anti-blister socks after last year’s ultra absolutely chewed my feet up. Tried a few different types, but recently came across Sums and they’ve been a solid find so far. I went for the extra cushioned versions, mainly because I tend to get hotspots later into long efforts. I’ve now used them on multiple 20-mile hikes and runs, and honestly, they’ve held up really well. Comfort-wise, they’re spot on — no slipping, no bunching, and they feel pretty plush without being overly bulky. Most importantly, I’ve had no real blister issues so far, which is a big change from previous experiences. That said, I haven’t pushed them yet in full ultra conditions, so that’ll be the real test. Overall, early impressions are really positive — comfortable, well-cushioned, and doing exactly what you want them to do over longer distances. Definitely promising going into the next ultra.
