Snowy days have met their match in the Bogs Kids Classic II Unicorn Awesome. Dependable waterproof rubber upper designed with four-way stretch inner bootie. Moisture-absorbing Max-Wick technology pulls perspiration away from little feet to keep them drier longer. DuraFresh technology shields against unwanted odors. Constructed with 7mm waterproof Bog Neo-Tech insulation. Comfort rated to -30F. Pull on style with grab handles. Removable insole. Please be advised that a white wax film may appear on the surface of the rubber boots and the brand states that it can be wiped off with a damp cloth. This "blooming" effect is not a defect. Blooming is caused when the boots are exposed to extreme temperatures or temperature swings and the wax helps prevent the rubber from weathering. Textile and synthetic upper. Textile lining and insole. Synthetic and leather outsole.
