As with velvet, brushing the surface of nubuck leather displaces the fibers and leaves a visible mark. Nubuck leather is very sensitive to moisture and color, and it therefore needs to be waterproofed.INSOLE: SUEDEThe flexible leather lining, which is gentle on the skin, nestles up softly against your foot and adjusts to its contour. The open-pored and thus very breathable surface makes for a comfortable foot climate, even during more strenuous physical activity.FOOTBED MATERIAL: CORKCork is a sustainable material extracted from the bark layer of the cork oak.
