This product seemed to be the perfect thing to wear around the house; they're made of organic cotton, so there are no chemicals in the material, and they have treads on the bottom, perfect for walking on slippery hardwood floors. Unfortunately, the treads are made from some kind of foul-smelling chemical that is strong enough to make a person gag (I got an instant headache)- obviously the manufacturer was cutting corners in the production of these socks. Too bad - it is a great idea, made bad by greed. Hopefully, someone else will use the same template, but with treads made from silicon or non-toxic rubber.
