Hmm.. I wear US13 adidas/nike/mizuno/newbalance/converse shoes so that means that I would need to look for the US12 Yonex shoes ? Darn it, the shops in Japan only have up to 29cm/US11 yonex shoes.. And the Yonex shoes here in NewZealand are total rip-offs, nearly three times the price of the ones in Japan. Do Yonex ratings go by the length of the feet? like for example I wore US12/30cm yonex shoes once and it fitted me quite well, since my left feet's length is 29cm and the right is 28.5cm, and that I need about 1cm of extra space by my toes..
