Providing grip and abrasion resistance, this Red Wing Nitrile sole will last a thousand miles. Cork nitrile is a rubber composite workboot sole that still has an exceptionally low profile. Mixing pieces of cork with the rubber saves some weight in the sole, without losing much in the way of durability. Cork soles usually lack a tread, so nothing you walk through will stick to your soles – including snow and ice suited to traditional boots, like Wolverines and Red Wings, the nitrile compound is very distinctive.
