The black Rieker mule 21064-01 is a classic shoe that you can always use. The two wide crossed straps are made of a material mix of imitation leather and textile and are decorated with sporty accessories such as rivets, a Rieker lettering and contrasting seams, which give the shoe its modern look. The mule is particularly comfortable to wear on warm days, as it has an insole made of breathable natural product leather.
