NikeMen's Tanjun Sneakers, Breathable Textile Uppers and Comfortable Lightweight Cushioning

When its say $40.32- $179.99 what does that mean ? Is it gonna be $42.32 or does it depend on the size. L?

Do these shoes run half a size smaller, bigger, or just exact?

are these shoes washable?

when I choose "9.5" (other than extra wide), is the width "medium" or "wide"?
