Lovely look and feel, good quality socks. Scored down as they are incredibly tight. Ordered size 8-10 (for size 10 feet) and were so tight restricted blood flow and were not comfortable to wear for long run.

Absolutely brilliant socks. Have a few pairs of theses and on a 100 mile race I only changed them once. No blisters and no rubbing. They kept my feet in good condition even though I had been through bogs and wet land over the course of the 100 miler. Even when moving uphill they did not move once. Can not recommend these socks enough.

These are my third pair of socks and I really enjoy them when out. I don’t have any problems or blisters during any long run.

My son and grandson love these socks. They are both cross country, half marathon, marathon and Ironman heroes. They haven't found anything else to compare these socks to. Great achievement 👏

Fantastic socks! Worn for a few long runs now and no blisters or pain. Before this I was getting blisters on many of my long runs so these have been an absolute game changer!

Unreal socks. One of my favourite brands, managed to snag a limited edition hat from Love Trails a couple of years ago which is now my prized possession. Don’t tumble dry!!! 🥲

Best trail running socks I've ever had. Perfect fit, function, comfort, durability. I've tried socks from every leading (and many a niche) maker of trail running shoes and apparel. And years of trial and error with brand after brand keeps leading me back to Sums as the champion.

The perfect running socks. They keep my feet blister free, they look good, and wash really well. I've bought many pairs for friends and family 10/10

Be been trying to find a sock that will be durable and keep blisters at bay. Recently started using some new shoes and they have been giving me blisters so the week before a race I was worried about these shoes ruining my feet….decided to give sums a go and they were brilliant!! I didn’t need any plasters on my feet just other socks on and had no issues for the first time in a long time so I’m happy!

The order was a gift. The branding all over the postal packaging ruined the surprise and now I've had five(!) promo emails in two weeks asking me for various things (which is on top of the two emails regarding purchase - fine with those). The socks are apparently fine. The shopping experience feels like dealing with some desperate and tactless beggar. Maybe try sourcing from another supplier.
