df01 pro absolutely~ no, you dont need to change size just pick the right length of your feet, lining and yonex has different number of size better u try first and buy the shoes at the shop instead of online shop
does df01 pro wider than 65z3? i wear 29cm 65z3, 28,5cm mizuno wave claw but online store only has 28,5cm df01pro
red one is the wide version, other color is normal U2.5 hmm, for that you have to try the shoes by yourself
