Heels for starting exotic

Hey, so I know you guys recommend only special pole dance heels but I’m on a tight budget, yet would love to start taking exotic classes after starting pole (fitness). I found almost identical looking platform heels 10x less than a price of pleasers (with good reviews).

Do you think it’s possible to take exotic classes with the “regular” heels when they look the same to my eye as the originals? Has anyone tried dancing in these kind of no-brand platform heels?
