Adjustable Heels? Yes hoặc No?

I tình yêu my stiletto, in fact, I have sacrificed a broken toe for them before. I, like may women, tình yêu 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 bạn think (be honest bạn won't hurt my feelings :) )! Thanks!
