Hi Andy - do you mean a Sports Equipment type shop? If so, there is a huge Sports Dominator along I/Drive - in fact I think there are a few different sports equipment shops along I/Drive. There are some Nike Factory Outlets - one in particular along the 192.
Sorry if this is not the type of store your meaning - but hope it helps.
I have several websites for the Malls etc - let me know if you want to browse on them and I'll dig them out for you
(I dont know if they have a branch in Orlando - but I found it on a search)
I am sure there are some more but I am a bit all over the place at the moment as we have just moved, but I am sure someone will post any more addresses if they are available.
