text: I got the 2E fitting since I wanted a wide shoe. I typically buy 4E in other shoes, However, this is wide enough. Note all Merrell shoes do not have Vibram soles that this model has. I did not get shoes with  moisture barrier since they make feet hotter and in California its hot enough and rarely wet. They did not require any break in.<br /><br />I have modified my review. The loose insole in the shoe is the cheapest I have ever seen and did not last. It is just a thin foam pad. It compares poorly to the inner sole of every other sports shoe and hiking shoe I own.
