A shoe that definitely deserves to be called a summer shoe is the brown Rieker men's slip-on shoe made of a mix of leather and imitation leather. Already at first sight you will notice the open hole pattern in the upper material. It ensures good air circulation and lets the pleasant summer breeze get to your feet. If you slip into the shoe barefoot, which is no problem thanks to the leather cover sole, you can feel this even better. The rubberized surface of the synthetic outsole and the two elastic inserts on the instep give you the grip and a firm stand you need in any situation.
