Would you pay for Height Boosters that hide inside your shoe so no one can tell?

Most height insoles are obvious. The second you take your shoes off at someone’s house it’s right there a thick block of foam, wrong shape, sticking out the sides. That’s the part that stops people buying them.
I’m working on insoles that fix that. Cut to fit your exact shoe and size, and printed to match the original insole…so if you’ve got AF1s it says Nike Air on it, fits perfect, looks factory. You still get the height, but if someone glances at your shoe there’s nothing to clock.
Thinking around $40–50 a pair, starting with one shoe model at a time.
Would you buy this? And if yes…which shoe would you want it for first, and what would you actually pay?
