For my dance I need Freeform lyrical dance shoes but all the ones I look at are like 40 dollars but I might not dance next year so I don't want to pay that much.
If you really aren't dancing next year and only need them for one dance, consider talking to the studio owner. Find out if you can borrow shoes from another student during your dance. Or maybe there was a student in your position last season who'd sell you their shoes.
If that doesn't work, you can buy the shoes, take really good care of them (aka only use at the show) and then sell them to someone else when your done.
