SUMS Avis 

Great socks! Worn for my first Olympic distance triathlon. Feet felt great in the heat.

The ease of navigating the website, finding out exactly what I wanted and what was in stock, was super easy. The color selection and sock styles were exactly what i was looking for. Will definitely be buying from Sums again.

This is now my 7th pair of SUMS socks, I bought the first pair for my first ultra 3 years ago and now they are my only running socks I use! All 7 pairs are still in rotation, I constantly recommend them to people! They are the best socks on the market!!

Arrived quickly, great fit. Bought a number of times now. 😊

I’ve been wearing SUMS for a few years now and will not run in anything else. Comfort, quality and excellent customer service put them head and shoulders above anyone else. Once you’ve run in a pair of SUMS - the white all-seasons will quickly become your go-to - you won’t go back.

Get involved.

Fantastic product. Makes a huge difference to my running. I'm not normally one to buy into these things but I bit the bullet and got a pair. I would definitely recommend these and will be buying another pair soon.

Great socks, fairly pricey though. And the marketing strategy gets you, almost pressuring you to purchase the bundle deal for greater savings and free postage! Unfortunately, I pulled a muscle in my calf during my first run wearing the Sums ! Nothing to do with the socks; the socks are the most comfortable I’ve ever worn!

Efficient service and quality product. The socks feel great to run in and I’m enjoying the colour schemes. Thank you!

I’m happy with my shopping experience with this company goods as described reasonably priced quick delivery would use again ……. Recommend

Sums socks are so comfortable, great material, high quality. I use them for all my runs. They stop me from getting blisters and they feel so light. I highly recommend.

Well packaged and quick delivery. Great quality socks. Gift for hubby. Well received. Thank you

I bought 3 pairs of running socks as a gift for my daughter. Very quick delivery and a quality product. This is the second time I have gifted her sums socks and she is very happy with them.

As someone who has been running for around 26 years, I am really impressed with these socks. The brand seems great: rewards, environmentally friendly packaging and cool vibe.

I have given these three stars because they are not bad socks, but my experience has been very mixed.

They look great and work well for shorter runs or everyday wear. Their odour control is excellent, and even after long periods in them, my feet have never smelled particularly bad.

I also wore them for around 10 hours during a UTMB event in very wet conditions and did not develop any blisters, which genuinely impressed me. They handled the moisture well and protected my feet when soaked.

However, I have struggled with them during longer dry runs and hot weather. The material feels very thin, rough and abrasive against my skin rather than soft.

After a hours, they can begin to feel like sandpaper and have caused some of the worst rubbing and blisters I have experienced from running socks.

They are also extremely tight, difficult to get on and off, and the merino pair shrank after washing. My feet can feel hot and irritated in them, although that may simply be down to how they fit my feet rather than a problem everyone will experience.

Overall, they are stylish socks with excellent odour control and they performed surprisingly well in very wet conditions. For shorter runs, they could be a good option. Unfortunately, they have not worked well for my feet during longer, hotter or drier activities.

Bought my first pair at Francis Running shop in Lisbon and had to buy more online. They are so comfy during my runs and I get so many compliments on the fun designs!

Easy to order, quick to arrive, great product.

My instagram account mainly consists of independent shops, retailers who are new and trying to get their feet off the ground and SUMS was one of them. Best find, best socks - going to order more!

SUMS customer care is second to none as are their socks. Been looking round for ages for the best running socks, happy to say I have now found them ⭐️⭐️⭐️⭐️⭐️

Great socks - I use them for running and hiking.
Wear well, wash well, good compression.
Only socks i would buy now for running and warm weather hiking.

Awesome socks! So good that I use them for running but also everyday too! Got the checkerboard pair and they are great socks. No blisters at all running!

I ordered x3 pairs in medium and 2 pairs arrived in the wrong size but Chloe from Customer Care replied super quickly and it was resolved very quickly too without any issues so big shout out to Chloe! Thank you!
