Stephen Yeung & Sebastian Thies of Germany's Nat-2 have created a truly innovative design in footwear. Nat-2s 'shoe within a shoes' are made so that when you become bored with, or simply too hot in your full coverage shoes, you simply zip off the outer layer to reveal an inner sandal hidden within. Nat-2 has many designs that are all made to be interchangeable with each other, which leads to endless options.
The 2-in-1 design is international patented by Nat-2 and the company says the shoes are handmade with the best materials.
They could open a footwear specialty store, entirely devoted to their sneaker concept.
