Not so different than your favorite pub appetizer, the Korkers Men's Greenback Felt Boot is a loaded with features that ultimately offer paramount performance, unparalleled traction, and solid comfort, so you can focus on the fish or lack thereof rather than your feet. The Greenbacks feature the Omnitrax Interchangeable Sole System and come fully equipped with a felt sole. However, the Greenbacks are compatible with other Korkers' specific interchangeable soles, so you can adapt your traction to meet the performance needs of each river system. The Greenbacks are constructed specifically for wet wading anglers with hydrophobic waterproof materials that reduce water absorption and overall weight, which also enables them to dry faster and in turn, assist in preventing the spread of invasive species. The cemented parts, strategic seam locations, toe caps, and web lace loops increase longevity. Iintegrated midsole drainage ports also allow water to drain quickly to keep the boots lighter while you wade.
