[DC] You are granted the powers of the Flash. What shoes on the market right now would last you the longest before disintegrating?

Any shoe that would normally last the longest under normal running conditions. Protection of his clothing, body, anyone he picks up and rescues, etc are part of the Flash's powers. 

Now, whether shoes would wear at all is an open question. They might wear down at the normal rate or they might not wear at all. If the Flash runs across the US, maybe his shoes wear down exactly the same as if you were to just go on a jogging trip the same distance. The powers might protect against extreme velocity, but not normal wear and tear.
