Well, I don't exactly live in Miami, I'm in Cali, but once you get their you might want to look for a "Big5" for sports gear or a "Footlocker" for atletic shoes. Sadly, that is as far as my knowlege goes. I've not really tried the different balls or shoes for that matter, so I couldn't point you in the right direction as far as brands go. I know Reebok are the primary shoes I use for sports, cause im cheap. lol but thats about all I know. Hopefully someone else will post too.

I posted this on Basil as well..I've been searching on the www and I noticed that Big5's are only at the Westside. The most European's footlocker aren't really extensive.. I'll give it a try in the US' 
And about the balls, I heard Wilson's are the best due quality, grip and price 
I might even buy two balls, one for balling inside, and the other for outside

Wilson! Now I remember, that's the brand I've used in the past. They arn't too expensive and they should do the trick. but then again, im cheap.
