The Birkenstock Kumba nubuck sandal with soft footbed in black is a real must-have this summer. The two crossed straps above the instep are adjustable so this sandal will fit perfectly to the foot. The straps are made of Birko-Flor, which is a long-lasting synthetic material with a beautiful patent layer. This sandal also has the well-known anatomically shaped cork foot bed with deep heel indentation, toe grip and latex layer.. The suede top layer gives a nice feel to the foot and is moisture absorbent, so that this sandal feels comfortable even on warm summer days. The Birkenstock Kumbu nubuck black with soft footbed is available in the width ‘normal’.
