I called Dinkles. They are in fact made in China now. I can't find a way to get a hold of Drillmaster but I guess I'll pick up a pair of them they seem to be the two top players. There is Gateway shoes but I don't really feel as if they are made to march...anyone have any experience with them?
Gateway Shoes : Tuxedo, Marching Band, Tap Dance, Ballet, Spats, Photo Purse, Photobag
