If the shoe doesn’t fit – PLEASE don’t wear it!

When I was little, when you went to the shoe store the salesman had a metal device with sliding ends he used to measure your feet.

As an adult, I don’t see very many of the measuring devices.  I wonder are these measuring devices extinct?  I ask this question because of the number of women I see wearing shoes that are either too big or too small.   Either is not good for your feet.  Your feet are supposed to be contained by the shoe 

I have worn Stuart Weitzman shoes for years and in his shoes I wear a size 10.  I can see a Stuart Weitzman shoe in a catalog, order it in a size 10 and know that it will fit perfectly.  I wear a size 11 in a Christian Louboutin.  Unfortunately, I don’t have as much experience with a Christian Louboutin Shoe, but, I am certainly working on it.
