The "Two In One" Shoes Are The Sandals.

German designers invented a kind of "deformation" shoes to help visitors cope with the changeable summer weather.

Deutsch news agency reported yesterday that the shoe was called "Nat-2".

When the weather changes suddenly, the wearer needs to open the zipper and remove the vamp so that canvas shoes can become sandals.

"Nat-2" was invented by Stephen Jan, the footwear designer.

When preparing for a trip, Yang asked himself, "why not design a fashionable, easy to travel, new shoes suitable for people to wear in limited urban space?"

He approached the K&T company in Munich, Germany, and turned the idea from a concept to a reality.

"We redefine the classic canvas shoes with the technology of two in one zipper with international patent," Yang said.

"Nat-2" dual-use deformation shoes were born.
