Have there been any Japan/Asian exclusive Yonex badminton shoes or colorways that do not release in North America? I know that in the past there has been but the discrepancy seems to be lessening each year to the point that I'm not sure there are any exclusives anymore. Does anyone know if there still is?
Yes. Go to a Japanese website, or say e78shop (.com) and have a look. There's always more offered to the JP market. For example, the eclipsion z2 has a 3rd option - grey with a mid cut for the ankle.
