OUCH - size 10 boots in large jets would be very tight. You'll find the XL Jets to be a correctly sized foot pocket and a lot larger blade (read "more power" lol)
If you like the fins, I wouldn't worry too much about your leg muscles as they will adapt very quickly after just a few dives in them (though in the meantime they'll complain a lot)
http://www.kidspot.org/personal/scuba has pictures of both the Large and XL Jets so you can compare the blade sizes.
Aloha, Tim
