Comfy, thin, supportive

These socks are so comfortable. Thin but very supportive.

The socks were not overrated

My feet were dry when I got off the tennis court. I will not buy another sock.

Extremely comfortable light-weight socks

These socks made my feet extremely happy from the first minute I put my feet into my walking shoes. They keep my feet dry and cool.

Pretty incredible...

I was in a shoe store trying on athletic shoes. I'm hard to fit and these particular shoes were great looking but something was missing in the fit. The sales person suggested OS1st TA4 Thin Air No Show Running Socks which they carried in the store so I bought a pair. The fit was amazing...the arch, the ventilation, the material and I could go on and on. I wore them the next day and ended up buying several more pair. The socks are a little costly but definitely worth it.
