The iconic laced rubber boots are designed in a 3/4 length, featuring a decorative D-ring at the center back and a logo on the shaft. The material can withstand temperatures down to –20° Celsius. If not treated regularly, natural rubber will develop a white surface over the years. This occurs because, over time, the rubber slowly loses its essential oils. To keep your boots in great condition for many years to come, we recommend treating them once a month with our oil.
