The Slipper makes of processing a good impression and feel when wearing and going good. He is insanely narrow and the instep flat. Since I have rather wide and high feet, I ordered it innately practical 2 no. Bigger but'm coming only with effort and shoehorn. If you put in it, it is as I said ok, but now just min. 3 cm long (I wear it only in the house and from time to time in going to the garage). Good that it expands, but wg. the overextension it not too long will like its predecessors also safe.
