text: I usually love Merrell Footwear...their durability, comfort and quality.  I love the upper shoe design and lightweight aspect, but after only 3 months of light use, the soles began to peel off the bottom, one section at a time. The sole is made of thin rubber like material and doesn't adhere properly to the rest of the shoe.  These trail running shoes were mostly worn indoors and and only a few times out on the trails, which is their intended purpose.  Design fail.  Durability fail.  Product fail.
