They'd probably all enjoy the Belz, it has all the usual designer sportswear outlets, Addidas, Nike, Reebok although there were a few shops closing down when we were over there at Christmas. If you want to have a look at what they have try this link.

As well as the annexes to the 2 malls, there is also another couple of rows of shops just before the Belz, with places like Bed, Bath Beyond, a bookstore, camera shop , Stamp Cabana (if anyone is into rubber stapming) etc.
