This is a 6" tall ribbed cuff version of our reknowned, padded foot wool sock. We started knitting the Woolie Boolie before wool was cool. The Woolie Boolie helped reignite a love for great wool by retaining all the positives of the natural fiber and none of the shortcomings. Itchy? No. Trusted companion on the most severe missions you go on? Yes. Our wool is grown, dyed and treated entirely in the United States. Very few companies can make this claim. They use wools that have to be shipped all over the world to be treated, dramatically increasing their carbon "footprint". We are thrilled to bring you this very special fiber. If a pair of socks has ever gotten close to having a true cult following, it's the Woolie Boolie. Sizing: Small (Women 6-8); Medium (Men 7-9.5 / Women 8.5-10.5); Large (Men 10-12 / Women 11-13); Extra-Large (Men 12-14).
