I've loved merrell's for years, amongst other top brand hiking boots.  When I started looking for a daily work out type outdoor shoe, these intrigued me the most from the other like shoes from competitors.  I've been wearing them for about two months for work outs, cardio, hiking, biking etc.  Love 'em!  They're very comfortable and have great grip from the soles. Looks as though the seams will continue to hold quite well.  My only prior complaints about my beloved Merrell hiking/backpacking boots are the seals that don't hold up and I have to shoe gloo them.  These have stitching through all of the outer seams and appear to be steadfast and durable.
