The Nexgrip Ice Anissa brings new heights and versatility to a classic boot, easy on-off and retractable studs for go-everywhere ease. On slippery outdoor surfaces, the cleat flips out for studded grip; when you return indoors flip in for a smooth sole. A must-have if you live in wintry weather and travel out and about. Perfect for commuters, students, ski resort workers - anyone whose day takes them indoors and out!
