German shoe company Nat-2 has internationally patented created a multi-functional shoe, a 2 in 1 concept. The shoe starts as a Converse Chuck Taylor style and zips off into a sandal. The interchangeability of the shoe is endless when put in combination with all the different models. you can simply zip off one section and replace it with one from another model to create a new look each time. I am really into this concept of convertible shoes.
