Not sure what you mean by fitting.  Obviously they'll work on the boots for you, that isn't going to change with size of foot.  If you mean finding boots in your size, a number of brands make some men's models with a 24.0 shell but you may need to get them ordered in for you because shops don't sell enough to order in a full selection.  You can also look into getting fitted for jr. racing boots, you get a quality boot but often save a couple hundred dollars.
