I'm an amateur runner. On average, run about 20 miles per week at a fairly good pace of 6-8 minutes/mile. Anyone would think that I go through a lot of shoes, but I don't. I have only changed shoes once in more than two years of running. All of my shoes have been asiics, which I can not stop recommending.

Now, what I have changed (like 6 times/shoe) are the insoles. Runners know that they are the secret to less injuries and comfortability. Right now, I have a pair of insoles that cost the same amount that the shoes did (and they weren't cheap). And worth every penny.

Do I need a product like this? No. Do I want it? I don't seem to see the real value in it. I guess you need to sell me better on it.

Now, if you could invent a passive sensor for my insoles then that would be great. Sort of like something that changes colors when the insole stops cushioning the impact as well as it should I would pay $50 for a reusable one.
