“We got these because my wife is training for the mountain to coast race from john o groats to lands end , with ultra running Ltd .. the race has cut off times and must be completed inside 17 days.. so the correct kit is essential, she tried a few socks all were fine for a single day ultra , but a epic event like this needs epic sock.. sums are that epic sock we will be buying 17 pairs for the race and another 10 pairs minimum for training.. they’re so comfortable everything about them spells class”
“First pair of Sums Running Socks. Took them out for a 14km this morning. Blisters from my run in Nike socks last week. These Sums socks were lightweight, breaathbble and very comfy. I’m sure I’ll be adding some more in the near future”
“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!”
