To keep our little trekker's feet cozy and dry on wintry treks, we have them slip on the Kamik Waterbug 5 Boot. The seam-sealed construction and impermeable material shield their feet from snow and slush, while the sole's flexible rubber and multi-directional lugs give them stabilizing traction that still lets them take natural, rolling strides. When the snow gets deeper, this pair's tall shaft and cinchable collar stop the fluff from packing in, and the synthetic lining holds in heat to keep their toes from going numb.
