Great quality socks. Perfect fit. Also just every purchases the Marino wool brown socks and they are brilliant while out on a cold/ wet trail run. Keeps the temperature perfect.

Really cool looking socks and always a perfect fit. I love the community aspect of giving back as you earn per run and that keeps me coming back. As well as the sock recycling scheme, I am slowly migrating to a Sums only drawer! Exceelent brand, ethos, communication and above all - product. Really good for for Trail, Road and Hiking. Follow the washing instructions that are clearly provided.

I bought these socks as part of my daughter's Christmas present. Yesterday, she called me to say how amazing they were, after her first trip of the year back to the gym. Thank you to Sums, ordering and delivery were seamless!

I bought these for my partner who has pretty much stuck to the same brand of socks for years. He’s said these socks are excellent, really nice close fit but super warm too. They’ve been tested in -10c!

I bought a pair in my son’s club colours. Outstanding quality and superior product. My son won an indoor 800m championship in them!

I’ve always suffered with blisters when running until I started using sums. Excellent sock for all running distances. I own various styles

You'd think Tina Turner made these socks as they are simply the best!

They seem to be a good running sock. They are nice and thin so not bulky in my trainers. I have only been for a couple of short runs and they seem a bit tight over the top of the foot. I am very happy to keep using them.
