Red Wing Shoes | Shoes | Red Wing Heritage 3375 Classic Moc 。Goodyear-welted with Vibram Christy soles. Made in USA. Factory seconds as indicated by the punch-hole in the tongue. This is due to a slight mismatch, with the right boot manufactured in 03/16 (with brown edge lining) and the left boot manufactured in 02/16 (with black edge lining). Both are size 9B and fit the same. The “B” indicates sizing for a narrow foot. In used condition with scuffs, however they are in very good shape for being 6 years old. Despite the mismatch on the edge lining, these are the same boot and fit the same and it’s not easy to spot when wearing. Boots are also unisex.
