ReebokUnisex Adult Classic Leather

I'm usually a size 9-9.5 in shoes. Just for reference im a 9 in Nike Tanjuns, do I order a 9, 9.5 or 10 in these shoes?? (Wide feet U.S.)

¿Porque me mandan un numero mas prqueño del que yo ordene vestias?

Do teenage boys where these? Is it in style for teens?

Are they made from real leather?
