The Rooz, as far as I know, will be approved until the end of the current registration period, end of August, I believe. After that, 300G will be the approved brand. They will have a trade-in program for PBA members who are using Rooz but cannot keep using them in PBA competition. As Rooz stock is depleted and new stock is produced, the 300G logo'd shoes will become available.
That's as far as I know.
