Prada Slingback with tie | Size 6 | wore twice

Prada patent pump slingback with tie, size 6 in white. Bought from Holt Renfrew a year ago for around CAD1000, only wore them twice (because I am a 6.5, I didn’t want to wait for the transfer. But 6 is too small and too painful for me to wear). Filmed the bottom for protection, and put it away for months. There is a ripped part on the right heel (don’t know how) and right shoes some stains from the dust bag :( hard to notice once you wear it, or maybe there’s some way to get rid of it.
