“Ran my first marathon in Sums yesterday- feet blister free and the socks were not on my mind at all on the run… as long runners might agree being able to forget about a piece of gear is a good sign it’s doing it’s job well!
The only thing I’ll say, is the extra large is maybe slightly too small for a 13, which one of my feet is. The other foot, a size 12 fits beautifully.
That said, I may feel like I ran a marathon yesterday, but my feet feel great!”
“Love this brand and their socks - always blister free and very comfortable for trail running and marathons! Highly recommend and the earn pet run is such a great initiative!”
“Been using SUMS running socks after struggling with blisters for ages, and they’ve been spot on. Really comfy, don’t move around, and I’ve had zero blisters since switching.”
“Excellent fit, quality craftsmanship, supportive customer care. Very impressive product and company! Lovely to run in, no hot spots, cool on the feet. Recommend big time!”
“Great product, expensive in theory, but worth the money when you rack up the miles and need a great reliable sock (for 10 miles plus as well as quick 3-6 mile runs) that won’t give you issues.”
“Best socks for running! When i first started running i used to wear cotton socks and used to get blisters most of the time. Whilst wearing sums ive never experienced any blisters. This is my 3rd pair now, they are a bit pricey but deffo worth the price”
“Bought the socks for my son for a ultra marathon
He’d been getting blisters
Once in his Sums he had no more blisters and a great run
Super buy
Great service
Thank you”
“Worth every penny, worn them trail running and road running and my albeit already quite chewed up feet have had no issues at all.
Great for wicking sweat but also a really robust layer when running through puddles/fording streams.
Picked up three pairs to try and will absolutely be buying a couple more! These are by far the BEST running socks I’ve tried…”
