With a very high 97% cotton rich knit, and using quality organically produced cotton yarns, these men’s Falke Brooklyn Organic Cotton Heavy Weight Socks are rugged yet soft-feeling boot socks. Cotton is naturally warm, yet breathable and moisture-absorbing, to help keep feet healthy. The socks have been made to a thick gauge, with a chunky feel and ribbed legs. Unlike many boot socks, these Falke socks have smooth toe seams for added comfort and protection from the rubbing that leads to blisters.
