These shoes look nice but they have a fundamental design flaw. They can crush your toes if you wear them longer than about an hour. And if you go a size up, it then slips off your feet. In the first few minutes, they might feel great and the sole seems nice and soft, but quickly you'll realize it's just an uncomfortable shoe.<br /><br />I can't attest to how long this shoe lasts, I haven't had it long enough.
