I possible, I would buy at least two sets of shoes to start to increase your odds of getting one set that works. It's also good to rotate shoes. I have flat feet. I've seen a website which provides a number for cushioning and stability, but I presume the cushioning value takes into account the insole of the shoe maker, which will be replaced by my orthotics. The Brooks Beast and Asics MC V look interesting, but I don't know to what extent their cushioning is reliant on the insole.
Any comments are welcome.
I have had orthotics made for the problem. I am running now at about 175 pounds. I claim no expertise in the matter, I'll just relate my understanding. Motion control comes from the ability of the shoe to guide the foot as it falls. Since cushioning isolates the foot from forces in the shoe, forces designed to guide the foot may also be isolated.
