Shoe design

Description:

I am looking to explore the idea of "reinventing" shoes. I'm looking to create a shoe that turns from a heel to a flat. In order to do so i need a mechanism for the heel to flip out and lock into place from a groove on the sole of the shoe. The heel itself would be based on a lever where you can push the heel into a groove of the bottom of the shoe to make the shoe a flat. Then click it out using a very simple unlocking system on the sides of the shoe ( a bit like when you unclick the lid of a calpol bottle pressing on both sides) to make it into a heel.

Wants:

Ideally what i am looking for is a mechanism that locks and unlocks a heel into place using 2 buttons on both sides of the shoe to be pressed to release. The heel must have a 90 degree flexibility and support the weight of a woman when clicked into place. To bring the heel into its groove again to make a shoe a flat, i would like to use the weight of a person to press down at an angle onto the heel a bit like a spring (using their feet as a force) in order to lock the heel back in.

Ask for Sample:

A sample would be great with a paper copy with a diagram showing how the sample was assembled together.
