I'm identifying the specific criteria by which people evaluate running shoes they try on.
The most important is "comfort." If you can't run your first mile in the shoe, you won't run 500. But comfort is very subjective so I'm trying to distill what exactly what means.
Here's the factors I think make up the characteristics of the shoe:
Responsiveness
Weight
Versatility (Can the shoe do tempo and long run?)
Cushion
Upper - Breathability and flexibility
Stability
The other factors come down to biological factors. If you have a wide foot, a narrow shoe won't work for you.
Am I missing other qualitative factors?
