New FP umpire - equipment questions

[Bluefoot]

I've been an ASA Slow Pitch-only umpire for the past few years. But this year, I'm probably going to start working high school NFHS games here in Connecticut.

As I am preparing to purchase all of the equipment that I'll need, I am wondering: Do we need to wear an athletic cup when we are working behind the plate during fast pitch? Or does just a supporter alone suffice?

Also, does anyone know where to purchase plate shoes in wide widths?

Thanks much.
