A well designed product

There are a lot of well designed products. Other than the obvious Apple creations, several objects are outstanding. "Seven for all mankind" jeans are well designed. They are cut perfectly to my body type, they are made of a rich looking, yet soft feeling fabric, and they are easy to use. No belts required.

Love it.

But pertaining to Norman's "The Design of Everyday Things," pointe shoes are the perfectly designed product. It is impossible to make an error putting on the shoes, because they are interchangeable right and left. They take advantage of natural mapping because they simply cover the shoes. There are many different types of pointe shoes, able to fit any foot, anywhere. Knowledge that one must keep in the head is how to tie the ribbons around the foot, but wait! Using the foot, there are only a couple of ways to tie the ribbons correctly! The knot of the ribbons must be tucked away in the inner ankle, or a forcing function will give you a blister!
