These are good, cheap, shoes for working out or any other applications where a beater shoe is useful. I am using them in a lab that can get messy and smelly and in which I have to be on my feet at least four hours at a time. They're going their job very well.<br /><br />The one thing I don't really like about them is the mesh upper. On the one hand, it feels really insubstantial. On the other, it's really insubstantial. It breathes well and doesn't feel flimsy. But it definitely isn't as nice as something like Primeknit or Flyknit.
