I had to return the last pair because the tread was DE-laminating from the sole.  Fortunately, the Amazon provider (Altrec) gave me a refund.  The should fit so nice and look so good, that I am giving them another try.  I read reviews on the last pair and several were from military personnel that claimed they were durable for Afghanistan , so I assumed they would wear well in an office situation...WRONG!  after only 5 months, the tread needed to be shoe gooed down. I paid such a steep price for them that I couldn't let it go. I expect Merrill's to fall apart and refuse to buy them anymore. I am hoping to have better luck with this pair. The lacing system is very handy and they look and feel great...hope they last a couple years indoors and since they are billed as trail runners, i expect them to be rugged enough to run carpet trails and linoleum halls with ease...or they will be going back ;-)
