Sort of. Mine are size 42, which is sometimes considered a 9, sometimes a 9.5 for American sizing. I've been able to fit into a 41 before, as well, and have shoes that are as small as an 8.5 for street wear. It's really more the shoe's fit than anything. I buy all my shoes (cycling, street) at the end of the day when my feet are more swollen, so I can determine if they are comfortable then. Theoretically, they should be comfortable all other times as well.
