Every woman loves shoes. Almost every woman loves high-heels. Almost every woman, who wears high-heels, is now and then bitching about them being uncomfortable or that you can't walk through mud or run fast with them.
The solution: The high-heel with detachable heels.
The basis for this invention is a regular ballerina-shoe:
To create a detachable high-heel, one has to face two very important questions that have to be answered before it is really an idea:
1. Where and how do I attach the heel?
2. When wearing a high-heel, the foot is 'folded' in a special way. (see next pic) This means the shoe has to be somehow flexible at the part right behind the toes, or it will break right there or even get you blisters.
The first question can be answered easily: The high heel will be attached to the heel of the shoe via screw&thread. Therefore the ballerina-shoe just needs slight modification. The sole near the heel has to be thickened a little bit so you can screw a screw in it. This wouldn't work with the basic, thin, flexible rubber sole.
The second problem is a little bit more complicated, but that's just where the interesting part begins. A small piece of the shoe, namely that one that will get bended in high-heel-position, has to be more flexible to not break. Therefore you take out a small piece (appr. 1 cm behind the rubber cap of the shoe on each side) of the un-flexible tissue, replacing it with a lamellar folded piece of tissue. This way the shoe will keep it's solidity in the flat-state and get more flexible at this point in the high-heel-state. Der Schuh behält so im flachen
I hope this will help every woman and at least one ambitioned Al Bundy.
