So far so good.
"Comfy sox. I wish they had thicker ones but I'm happy with the order and will be ordering more. I appreciate a brand that backs their products with a lifetime warranty."

"Comfy sox. I wish they had thicker ones but I'm happy with the order and will be ordering more. I appreciate a brand that backs their products with a lifetime warranty."
"Gifted approx. 8 pair to men & women. All grateful, so they said. I love these."
"A pretty good sock. Five stars if there were more compression"
"The socks are great quality and would highly recommend them to anyone looking for hiking socks, I own multiple pairs"
"Good socks probably going to order som more"
"Provides good cushion and they seem to breathe well."
"I loved these socks since the first time I ordered back in 2017. I've since had several pair and cloudline definitely stands behind their product in case of holes or damage. I actually just found a hole in one of my socks so I will be contacting cloudline for a replacement. I wear the ankle docks with sneakers in the summer as well. Highly recommend these socks for many reasons. I have never had stinky socks either with the antimicrobial factor with these socks."
"Soft, well padded but not too much, warm but not sweaty. Will be purchasing more."
"Warm but not hot and comfortable"
"I only wear cloud line socks. I have moderate foot nerve pain and these socks actually make a noticeable difference for me. I wear different heights and colors for different shoes and functions and even wear black ones with my dress shoes. It is the way to go!"
