It depends on what brand you are talking about. Mizuno/Asics: No, they are separate lines Adidad/Nike/Hi-Tec: Peobably yes. They have only those "indoor" court shoes. Yonex: No volleyball Shoes. Wilson: same indoor shoes for their squash, badminton, and racketball lines. Could other BFers add some more brands? -SC
In general volleyball shoes are heavier than the badminton ones, but does provide more cushion, if from nameable brands.
I use my SHB 99 MX's for badminton but as well for volleyball, i find they work great. No problems to this point, and seems to have everything a volleyball and badminton shoe needs...
I use the Mizuno Wavelightening volleyball shoes for my badminton games. I think they work fine for me. I never really tried out the badminton shoes but I feel volleyball shoes will work just fine.
