Current line of Wilson tennis shoes?

Hi,

I need to find out what shoe in the Wilson line is now the equivalent of the Prostaff 1000 they stopped making and I used to wear for years. My feet have problems and while I dont play tennis much these days I pretty much just wear tennis shoes all the time. . . :D

I also live in an area where its hard to find nonmainstream shoes so I now order online and that makes things tougher when you need to try on a shoe. . .

Thanks!
