Built for active winter play, the Trek Kid keeps little adventurers warm and comfortable for hours in the snow. Ultralight and easy to move in, with a natural zero-drop sole and wide toe box that lets growing feet move freely. Kids slip them on themselves thanks to the wide opening and one-hand drawstring—no laces or buckles needed. Insulated to -50°C/-58°F with a water-repellent upper that sheds snow and slush. The removable liner lifts out for easy drying and cleaning after every muddy expedition.
