What type of organic certification do the socks have (i.e. OCS or GOTS)? How tight are they around the leg?
The socks are made from sustainably grown and harvested GOTS Certified organic cotton. The rough sizing on the top of the sock is about 3 inches flat (6 total) without stretching. With the stretch (needed for sock to stay up) is 5"x2= approx. 10".
