Best socks I’ve worn yet, and just wore them in the Edinburgh Marathon. Felt comfortable and held feet in shoes with no rubbing or blisters. Quality socks 🙌🏻

I’m honestly not one to usually leave reviews. I bought these as I was running the Leeds marathon, I ordered them a bit late so they didn’t arrive in time for that (that’s on me, not the complaint). I have since used these for only 2 runs and they are falling apart. Not sure if mines a one off, but as it stands, for the price would not recommend.

I have used Sums for my ultra prep and I dread to think what condition my feet would be in without them. I am still yet to of lost a toe nail or gained a blister, would definitively recommend to anyone getting the miles in. I will be wearing them on the big day 💙👊

I’ve been eyeing some socks from Sums for a while now. One night, I decided to take the plunge and buy them! I’m so glad I did! The quality of the socks, the design, and the efficiency of delivery are all excellent. I also love that I’m now part of the Sums Club, where I can earn points through my Strava account and get discounts on future sock purchases. It’s amazing! I’m definitely going to be purchasing again soon.

These genuinely have made a difference with the thinker rubbing protector on my Achilles. Absolute charm

Ibought two pairs of the All seasons in White. I have only worn one pair so far and this is my experience: The foot is a great fit, snug, no movement, a nice compression that keeps the foot in place. The cuff is a bit too tight. Also a bit too low, but this is more of a personal opinion. Also, personal opinion, more white socks would be great.

Great socks, airy and breathable but with support and cushioning in all the right places. Love these socks!

I was given my first pair of Sums as a present and found so comfortable, in my head they improved my run so purchased a couple more pairs. Ran 1/2 Marathon in the rain & no blisters or sore feet!

Love the style/colours and they’re clearly well made. Wanted so much to love these, but I really struggle with the size - I’m a UK 11.5 (standard width) and the L socks are a battle to get on, harder than my compression socks even. Can’t help but feel like they’re needs to be an XL :(

Really comfortable, great colours and thick enough to hopefully last! Bought my first three pairs but I have a feeling I will be back for more when new designs are released
