Sperry boots with tan, green and black exterior. Warm shearling lining. Durable design. Flannel-lined with 200G Thinsulate Fully waterproof Waterproof rubber shell keeps feet dry Ceramic lug outsole for grip Rugged, resilient, ready for it all: the Ice Bay is Sperry's most formidable winter boot yet. I’ve used these a handful of times and loved them, however, they proved to be too big. They are true to size and I’m usually a 10, I wanted more room for thick socks but this was too much room and I missed the return window. I’d consider these in very good used condition. Non-smoking home.
