I am currently working on creating a portable rollable ballerina flat which can be easily transported in a women's purse and utilized as a backup pair of shoes when pain resulting from wearing high heeled shoes occurs. The reason for my inquiry is I am looking for a material to use to create a sole which can be both very thin and flexible while providing protection to the foot while walking outdoors. The material must be low cost as well, as this product is an inexpensive one.
At this link you can find a picture of a rollable ballerina flat, so you have an idea of what I am talking about.
Anybody's help is greatly appreciated!!!
