Can I use Vans Water and Stain Shield on Converse

So I just got my first pair of Vans yesterday, they're the Nintendo SK8-Hi Reissue Controller ones. I don't skate, just liked how they looked and felt. It's my first pair of shoes over $40 (ended up costing over $80) and thus I want them to last forever. I was persuaded to buy a can of Water and Stain Shield at the register, but now I'm worried about applying them. The website says that the shoes are canvas and suede, I don't know much about fabrics but I do notice that part of the shoes have this really nice fuzzy finish that I don't want to ruin. Will the spray harden the shoes' surface in order to render them waterproof, or something like that? On that note, what if they get wet without the spray on? Can you wash these shoes (I'm used to throwing my shoes in the washing machine if they get dirty)? What is some basic maintenance I should know?

Tl;dr: Bought the Nintendo SK8-His. Because of how expensive and limited edition they were, I want them to last forever. Should I apply the spray?
