A couple hours of the high life, and they really can produce a stink.

Cheaper shoes absorb and hold more sweat, so they also give the bacteria more to grow on for every wearing.

The best solution, I've found, is to use some sort of disinfectant in the shoes after every wearing. A basic Lysol type spray is just fine. My teenagers have always done this, and it works great.
