Is a batter's lost shoe detached offensive equipment?

I should add that in the NCAA, there is an actual rule, 9.7, that defines Equipment Blocked Ball. It says:

9.7.1 No loose equipment (that is, gloves/mitts, hats, helmets, jackets, balls, on-deck batter’s bats), miscellaneous items, or detached parts of a player’s uniform, other than that being legally used in the game at the time, should be within playable territory as it could cause a blocked ball. Official equipment that may be within playable territory with no effect includes the batter’s bat, the catcher’s mask or helmet, umpire paraphernalia, and any helmet that has inadvertently fallen off an offensive or defensive player during the course of play.

There is no mention of a player's shoes as official equipment that would have no effect on a ball that contacts it. So in NCAA play, your scenario would result in a blocked ball. I guess they feel that shoes be designed to not come off a player's feet.
