“There are socks and then there socks that you hope will be different, will deliver something that you know youre feet are missing when you go out for a run but you just cant quite put your finger on what it is that is missing......and then Sums come into your life and the first time you put them on you go "yessss, ive found them". Im still not sure what it is that makes them give that "Yes" factor but they do and they do it in spades.”

“I can’t praise SUMS socks enough! I had many pairs and they’re incredibly comfortable and hard wearing, ran many races and never had a blisters or hot feet. They look awesome and I genuinely wouldn’t wear anything else!”

“Bought my first pair of these socks after getting blisters on an ultra run. I really like the quality and feel of them, and so far I’ve been completely blister-free! 🙌 So, naturally, I had to purchase a few more 😂 And now they’ve brought out ankle socks… I couldn’t resist buying even more! 😂🧦 Really impressed with them and would definitely recommend! 👍”

“I got the new SUMS Quarter Crews in lilac and they’re honestly stunning! Super soft, supportive and really comfortable, with just the right amount of cushioning. I’ve recommended them to ALL my running pals because I genuinely love them. I also have the LoveTrails special editions as my trail socks and they’re a solid 10/10 too! 💙”

“Ordered 3 pairs of Socks and they’re easily the most comfortable and supportive socks I have for running. I use them for every run I do. Won’t be using any other brand again!”

“Bought four pairs of these socks in size large. I’m a size 9, so I thought these would be the right fit. Unfortunately, I’ve found the socks incredibly tight around the middle of my foot. After a few kilometres, they become very uncomfortable to the point that I had to stop my run, go back, and change into an old pair of running socks. I’m very disappointed with these. The advert promised so much, but unfortunately they just didn’t work for me. Having bought four pairs and already disposed of the packaging, I can’t send them back, so into the bin they go.”
