100% Waterproof & Built Tough. Our men's gumboots have the essential attributes for gardening and general outdoors work. All of our gumboots are 100% waterproof, rubber, and most importantly, neoprene lined. Our range has been selected because these men's boots are NOT flat soled nor cotton lined, as are many uncomfortable men's boots. Our boots are internally contoured with arch support. A steel lugg has been inserted midsole for strength. The neoprene lining ventilates the feet. The tread provides maximum performance. Please review our specific description for each boot below.
