That's what I was thinking. Those big bent end calipers that would easily extend into the shoe without having to cut anything. I'm fairly certain that is what they measure running shoes with.
In some cases, I think that shoe manufacturers are now providing the information themselves. I know Altra and Newton brag about having zero drop shoes and even big name makers like New Balance are turning out running shoes with very minimal drop or zero drop.
