Polyurethane footbed Upper: nubuck leather Footbed lining: suede Sole: polyurethane (PU) Heel type: wedge heel, heel height: 40 mm Details: two straps, each with an individually adjustable metal pin buckle Made in Portugal UPPER: NUBUCK Nubuck leather has a gently buffed surface with no grains. 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: REAL LEATHER The 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: POLYURETHANE Polyurethane, also known as PU, is a synthetic material ideally suited for use outdoors. It is water-repellent and dirt-resistant and very easy to care for WORN ONE.
