Tough to rate on anything else. I did not realize Birkenstock got into so many different materials, each with their own costs. I think it fits great. )The quality is good. Plus you enjoy its great design. I accept no responsibility for your actions. Run small- I normally wear 7-7. When I wear my Cortez I like to complete the look with other retro pieces like bell bottoms or retro t-shirts. Best keyboard ever, comfy arm rest glad I got this version, wonderful chroma effects and you can create your own, great key press although if you don’t like clicky sounds this isn’t the keyboard for you. This is just what Ive been looking for.
