Wei-Chieh Tu's height-adjustable shoes can be raised through a 38-()() angle and locked to meet the shifting needs of your feet. You can wear 0-()()-38-()() as a flat shoe while dashing to the office, release the heel to a halfway height for comfort throughout the workday and, when evening falls, max out the heel for a more glamourous look.

I wanted to write about the adjustable shoes, forgot about them, then remembered when I saw this awesome creation of Ukranian designer Andre Tan.
