Work in garage on cement and outside in Pa. Snow, rain,cold, heat, these boots are all- around great. after 1st pair I ordered 2 more pair . have started breaking in 3rd pair. Have gotten 3-4 years out of each pair of boots, wear them 6 days a week , 49- 50 wks a year. Care is Kiwi leather polish every 1-2 weeks. Bates quit making this boot w/ thinsulate and is only available w/ gortex. The gortex -thinsulate w/ durashock sole made a great liteweight combo that kept your feet protected from damp -cold- hard cement and the PA. winter elements.
