Leder – Bok
Leder-Bök® spray gives an invisible protective coating to suedes and nubucks, it nourishes and proofs the upper, and will extend the functional life of the boot, if used regularly. Leder-Bök® can be used along with Leder-Gris® to give a higher level of water repellency on Nubuck boots (not suede). The Nubuck finish is changed once Leder-Gris® is used and the change is not reversible. See Suede and Nubuck User Guide for further details.
