No need to worry about slipping in NexGrip’s 'Ice Victor 3.0' six-inch outdoor boot. Its treaded sole is made of an anti-slip compound and has a patented retractable stainless steel cleat that flips down to bite into ice in extreme weather and flips back out of the way for normal wear. The waterproof leather-and-suede upper laces up the way you like it but has an inconspicuous waterproof side zipper for easy access after that. Membrane waterproofing and Thinsulate insulation rated to -31 degrees Fahrenheit. Removable fleece-topped foam insole.
