I spend 90+ % of my waking hours wearing flip flops. Yeah, I know I'm lucky. I loved my soon to be two year old Teva Deckers (first Tevas I have owned) so much I looked for a new pair. Unfortunately, Teva in what now appears to be their incompetent managements wisdom - has chosen not to make them anymore - so I compromised for the Mush II - big mistake and disappointment. My problems with the Mush Ii are the following:
1. Though my Deckers and the Mush II are size 10 - the Mush II is more than 3/4 of an inch shorter and 3/8" narrower than the Deckers - which fit perfectly. The Mush II is too small. They fit my wife.
2. In the Amazon photos the Mush II - Dune model has what appears to a shade of olive green faded straps which I was fine with. In reality the straps are faded tan or beige - and but ugly.
3. Not are the straps faded and ugly, but they are made of cotton which will not last if wear these in wet environments - cotton rots quickly when wet frequently.
My conclusion is that I either got lucky with my Teva Deckers - or Teva has lost all quality control and design abilities, competence and their current business model is ripoff their loyal customers.  Mush II is no better than the $7.00 flops I also have, surely won't last any longer - and apparently made by the same incompetent factories. Very disappointed. My wife says she will give me $ 5.00 for them and sew some embroidered ribbon over the straps so they aren't so but ugly.
