“I was sucked into the SUMs world because of the story behind the brand. The pledge-per-run is something I loved about the company but to be honest, I wasn’t sure if the socks themselves would follow suit. So I bought a few pairs and man did they prove me wrong… I’m currently training for a 50k Ultra and I’ve worn my SUMs for every run so far. I’m 100’s of miles in and I’ve had no issues with blisters and the padding in the heel is super comfy. I would highly recommend trying them out if you want a decent sock that’s making change in the world every step at a time!”
“Great socks, really quick delivery and lovely packaging! Socks fit great and no blisters or rubbing so far so doing what they promised! Massively recommend!”
“Fantastic customer service from the team. I had originally ordered the wrong size, and then emailed the team who promptly sent out a replacement pair, all within 2 working days!”
“The product itself is good. But I didn’t like that I had to pay for delivery twice - on your website and at the post office. Overall the price of the delivery was disappointing.”
“I was so excited to run in them I had to go out and take them for a spin as soon as they arrived. I was not disappointed! Very good fit and nice compression!”
“Purchased these socks for my long runs to help with preventing blisters as I’d heard great things about the brand and design, so I was excited to try them. Unfortunately I was disappointed that after my first time wearing them, I did get a large blister on my arch immediately. There’s cushioning on the outer sides for your feet but if you suffer from blisters on the inside of your arch, then sadly they don’t protect this area all too well. I’ll be using my double layer socks for long runs now - which is sad as I love everything else about the sock!”
“Incredibly comfortable, breathable and lightweight. Perfect blister protection and very reasonably priced. What’s not to like about SUMS? These are great socks.”
“Discovered on Instagram. Perfectly targeted. Extremely pleasant shopping experience. Socks are so comfy & I will be running the London marathon with them! 10/10”
“I bought a pair for a friend who was doing a marathon. This was his feedback:
Sums socks are amazing! Didn’t have chance to trial them before the marathon so just went for it. They were perfect and better than any pair I have worn running before. Thank you very much.”
