***UPDATE on 4th pair***
5 weeks use and blow out on both sides of show.  Less mileage put into this pair.  Return date is 4 weeks... and missed it by 1 week.
 Complete disappointment on this pair.  $38 is a good deal, if you get more than 5 weeks use.  Previously averaging 3 - 5 months use out of each previous pair.

My husband works as a mail handler for the usps (averaging 20k steps a shift). These shoes have outstanding wear and comfort...averaging him 4 months use per pair.
