dyeable shoes

Hi ladies! I bought Coloriffics for my wedding shoes. I'm going to be wearing them white for the wedding. I'm hoping to dye them black after the wedding so I can use them again.

Does anyone know of a shoe store that will dye them after the fact, even if I did not buy them at a store? ( i bought them online)

TIA!

I got mine dyed at Sandy's in Massapequa Park.

ETA: I didn't buy them there, and it was like $25 bucks.
