Boot was extremely comfortable but after 6 months of use the sole split. I returned them to the Keen garage of purchase and was told they'd cover it as warranty, but it was a wear issue. I've owned Wolverine, Danner, Thorogood and Cat boots over the years and never had a sole tear in half from use. I wouldn't recommend Keen boots to anyone who actually works in the field. This boot is made for general foremen or project managers, not those in the trenches.
