Meanwhile my felt twentieth pair of ballerinas. They are super comfortable and are even worn by me in city trips: never get a blister or foot pain of it. Since they are worn almost daily by me in the summer, their shelf life is usually two summer. The leather is outside repelled a bit in some places and the shoes sit no longer optimal. In black suede can help out with colored leather care a bit. I buy these ballerinas only on Amazon, because prices but clearly distinguished from the shoe store. I have quite narrow feet and regular size 40. The brand Buffalo corresponds to 40 then actually 40th A strong buy recommendation for this shoe classic!
