Good overall service & communication

Good overall service & communication. Socks were OK for local trails up to 10 miles but soon had to change into my twin-layer reliable trail socks as I could feel hot spots forming. Definitely no where near ultra distance comfort so relegated to spare sock bag after one use or for the gym.

Cool chequered socks

Cool chequered socks. The compression socks are a little too tight on my calves though, I'm not particularly big but got fairly large calves. Might be good to have different sizes based on calf diameter

Awesome sauce socks!!!

The socks are greay and actually help with my running. I don't have any blisters anymore and the socks are really light and great quality and they look great as well.

I also really like the rewards scheme where every run that you do on Strava. They potentially would donate money to your nominated charity, which I think is a great thing to do.
