Buying shoes should become easier

It should be same as buying packaged food items/electronic gadgets.
But rather it's like buying clothes.

What I mean is, there should be a model number for every shoe type,
so that the prices can be compared across the stores.
At least from the manufacturers who are selling abnormally expensive
shoes, for e.g. : Adidas, Nike & Reebok.

Then there should be a leaflet, explaining the material used in the shoe.

With the kind of prices they have touched these days,
they need to give the customer a better picture of what's
being sold.
