The Kids' Winter Apex Boot is the latest Muck Boot built to keep little ones warm, dry, protected through winter's toughest conditions. This 10inch waterproof pull-on boot features a drawstring cord to keep warmth in and cold (and snow) out. This kids' winter boot also sports 2mm of Neoprene and a warm fleece lining to keep tiny toes comfortable as the temperatures drop. The lugged rubber cup outsole is designed for all terrain traction, allowing kids to explore nature's classroom no matter what lies ahead.
