Performance Sock Black

TA4 functional socks use OS1st's latest technology ThinAir, to create as airy and comfortable a sock as possible. With a very thin and airy top and a more padded underside, the result is cool with maximum comfort. We use OS1's patented technology for compression zones to create an anatomical fit and counteract chafing. If you need more relief for injury / inflammation, you should look at the product FS4 from OS1st. TA4 is suitable for everyone who wants a comfortable and airy sock for training as well as everyday.
