I have a pair of original black Moab I bought 5 years ago, still in the box unworn. I've been wearing a pair of brown ones all this time that the soles have worn down now to smooth. Decided to get a pair of Moab 2 in a different color. Didn't feel like wearing the black ones right now. I've worn Merrell Moab for a long time now, because they run narrow and I have a B width foot. Other reviewers mentioned changes to the Moab 2, so I got my new old style out of the box and compared. There is one less shoestring hole on each side, but the top hole is in the same location. The other difference that stands out, is the back of the shoe. I measured the backs of both styles, and the original Moab is 1/2 inch taller then the Moab 2. The back is also designed a little different. I tried the new ones on and walked around the room, and didn't notice any difference in feel. My heel felt secure in the shoe without slipping. At this point I don't see any reason the new style won't work. If I knew how to post a picture comparing the differences, I would have.
