Innovative and imaginative design of new shoes

In the shoe cabinet of each mall, there will be a variety of shoes on display. Although there are many styles, the so-called differences are just a change of color, or only make some adjustments and changes in detail. After years, decades, even several decades, the shoes we wear under our feet have not changed too much. There are obviously not few people with this idea, they also designed new shoes with their own ideas, and the styles can be said to be various, some are bold, some are environmental protection. Personalities are apparently not lacking, but... Is it comfortable to wear such shoes?
