Going to invest in actual Badminton shoes, (yay). I already slightly hurt my ankle, so, decided I better get some. I narrowed it down, as many others, to SHB03, 65z (High-End) Or some Asics/Mizuno/Cheap Yonex (Mid-End) My question is: Do the high-ends really produce that much difference in a competitive game/tourney? An alternative is investing in a mid-end for practices, and the high-end only for competitive games. Good or bad idea? (Usually play on gym floor, not real badminton court.) Finally, what are the differences between all the models of SHB03, like SHB03z (red/orange) or the SHB03EX (whiteish), and etc?
