Beautiful and attractive sock that runs small and the ankle is too tight. Unfortunately, this sock and I are not compatible.

The Best!

I ran several marathons in Fitsock CX3 socks, along with a number of long training runs. Never once did I get a blister while wearing them. In my experience, thin, snug-fitting socks prevent hot spots better than thick socks. As for "cushioning", I'll get that from the right running shoes. I don't need a sock company adding in layers of yarn, thank you.

Gobros shipped lightning fast, and the order was accurate. Fitsock + Gobros will be my go-to on a go-forward basis!

Great running socks overall. Soft, good heat and moisture management and excellent form fit.

I love Go Bro’s!

FAST service! Love that I can get my Fitsoks 1/4 sucks from a local source. I can’t find these running socks in any store locally or otherwise. Thanks for carrying them:blush:
