The iconic laced rubber [[boots]] by ILSE JACOBSEN HORNBÃK. These knee length rain [[boots]] features a decorative D-ring at center back and logo on the shaft. These wellingtons are made of sustainably harvested natural rubber and have been cut by hand. This material can withstand temperatures down to -20 degrees Celsius. The rubber composition is 80% pure, natural rubber and 20% secret formula. Entirely PVC-free, our [[boots]] contain no animal by-products. If not treated regularly, natural rubber will develop a white surface over the years. This is simply because the rubber will lose its essential oil. To keep your [[boots]] in great condition for many years to come, we recommend that you treat them once a month with our oil. New laces are available in several colours.
