These Red Wing Heritage 1907 Classic Moc 6" boots are made out of Copper Rough and Tough leather, one of Red Wing's most popular leathers. The oils used in the tanning process make for an incredibly tough leather that will age beautifully over time. These boots feature a Goodyear-like welt and the always comfortable Traction Tread rubber outsole. Red Wing has been making Moc Toe boots since the 1950's and there's a reason they're still made today. They're just damn good boots.
