I have gone through three pairs of these shoes at $130 a pair.  If you decide to wear them 3-4 days a week expect to wear them out in 6 months.  The shoes have a very thin rubber sole that wears easily.  Don't believe me? go to their website and read this... [...] Look under questions to see the first question is ... "How do i get a new sole"

Love the shoes, most comfortable I have ever owned next to crocs...But can't justify another pair.
