I have used defeet socks for years. Love the high visibility. I was on a ride a few years ago and i could see a guy from a mile up the road with these going up and down. I thought they would be a good idea, but i didn't realize they feel almost like a compression sock. Very supportive. love them.
These socks are very comfortable especially with my riding sandals. I especially like the hi-vis color which hopefully helps make me more visible on the road. Not sure how they make these things out of "recycled water bottles", but keep up the good work!
The socks are great for warm weather rides and help increase you visibility to others while on the road. Have worn them for several 40 + mile rides and find they are very comfortable.
