During a recent trek to Mt Wittenberg, I got a 1/16" dent in the leather by the toe. It looks like it goes down to the plastic (steel?) toe protector. The leather around it is fine, but am wondering how to best care for the boots. A guide recommended spray rubber. Have others done this with their leather boots?
