These socks are amazing! Blisters on the sole of my foot were a bug issue and if tried other brands and wrapping them in bandages but nothing worked. Since investing in SUMS I haven't had a single blister. They're brilliant!

Great quality sock with superb support. Only a small thing but as they are tight on the skin it can be hard to adjust them when putting on.

Great socks . I've been running for 40 years and I think they are the best I've had. Buy a single pair to try then buy in bulk to save money .

I love these socks!!! They are so comfy and the styles are so cool, I struggle to wear anything else (though best to save them for long runs because they are too good at looking after your feet!)

The best running socks out there. I couldn’t wear anything else now that I have tried SUMS- if you’re on the fence about getting a pair, this is your sign!

Love my sums socks, initially bought two pairs for marathon training as my shoes were giving me grief and rubbing with a variety of different running socks. Since I have bought 4 more pairs and no problems. Completed Venice marathon last Sunday and despite the distance and my shoes being socked through from areas of Venice flooding causing all the runners to wade through water about 30cm deep, no blisters or problems!

Love my SUMS socks. They fit perfectly and I don’t suffer from blisters on my runs. Good quality product and stylish too!

Adore them so much! I wear Norda shoes which I love but they do cause blisters. These socks stopped that entirely!

Purchased around 10 pairs now. Favourite socks for running. No slippage and very comfortable.

Fit well and genuinely not as bad for blisters as my regular sport socks!

I’m a running coach and have tried a lot of socks but I loved SUMS so much I bought a second pair for me (these were actually a free pair because I return an old pair in the free envelope), two for my husband, a pair for both my sisters and one for a friend. So comfortable to slip on. I’ll 100% be wearing these to run Valencia marathon in December.
