Adjustable Heels? Yes 또는 No?

I 사랑 my stiletto, in fact, I have sacrificed a broken toe for them before. I, like may women, 사랑 my shoes and wouldn't give them up for anything, but if I could choose to have comfort and fashion why not? So, for my business class we had to come up for an idea for a re-design of a product and see if it would be marketable. Here is my idea for a new shoe with adjustable heels. Let me know what 당신 think (be honest 당신 won't hurt my feelings :) )! Thanks!
