Incredible. Not sure how they've managed to crack this code but running long distance in these socks is a pleasure compared to previous socks I've ran in.

The socks were a gift for my brother who runs marathons all year long. He is delighted with them. I was impressed at the customer service and swift delivery as well as the accompanying fitness training advice I have since received.

The quality of the products is great and I really like the approach you have to recycling old running socks, regardless of brand.

Picked these up as I’ve been training for an ultra and as the volumes increased I’ve been suffering with some pretty severe blisters. Worn these on every long run since and I’ve had nothing since 🙌 will be getting another couple pairs for sure

After finding out about Sums from the ‘That’s Runnable’ podcast I purchased 3 pairs of socks and they’ve really helped stop the blisters I was getting from long runs previously and they are comfy too! Really loved finding out about the company and what they stand for. Would recommend!

I’ve used many different types of socks that have promised no blisters, can do this and that. First time wearing the socks yesterday and can honestly say these socks have delivered. Comfy, no hot spots whilst running. Feet felt at the end of the run fresh and ready for the day ahead

I’m up to my 5th or 6th pair of All Seasons. Can’t run in anything else now. SUMS or none. If you don’t have any yet, get involved. Couldn’t recommend more, customer service team are ace too.

Possibly the best socks I have ran in. Always struggled with finding sock with the right amount of compression. Sums socks give me the right amount of compression and feel like you don't have them on. No sight of blisters at all and let your feet breathe so don't overheat.

Some of the best running socks on the market and affordable. I own multiple pairs and they've helped massively with my 10k and half marathon training

I love these socks! Such a game changer. I haven't tried running socks before and I didn't realise what a difference they could make. They make my feet feel secure and supported and the designs are great. Will be back for more.

When I first started running, I noticed a friend wearing Sums socks and thought they looked so cool. I haven’t seen another brand quite like them! The extra padding is a game changer – no blisters, just comfort – and I love that the brand also gives back to charity. Running, but make it fashion. Obsessed!
