Mime Et Moi has designed what may be the most versatile shoe to date. The height adjustment function allows you to change the look, comfort, and style of your shoe throughout the day.
The way it works is that there's a lever placed inside the outer sole, which you pull to remove the heel. When you press back down on the new heel, it locks it into place, adjusting the style of the shoe in seconds.
