I bought these Kempa Court shoes for squash. I've used them just once as they're slightly too small for me. I'm usually a 10/10.5. They say they're an 11 but they're not, so despite their label I've listed them as a 10. I think they'd fit someone usually taking no larger than a 10. Even perhaps a 9 if you like lots of room. They're great shoes, just slightly too tight for comfort for me.
