First I have to admit upfront that I am a long-time user and fan of Merrills. This is probably my fifteenth or so pair Of either Merrells Cross trainers or comfort shoes. This pair ranks up with the best. Transparency forces me to tell however that I also buy other insoles. Not that Merrells isn't comfortable. I just opt for ones offering me a touch more comfort and support.

Updated: 5/24/18 - First pair of Merrell's that I have found the size not to its standard 9.5M fitting. After the initial five or six wearings the pair did not loosen up as I usually find them to do and feel tight and uncomfortable after just short walks or jogs. I thought maybe I had ordered the wrong size but no, size 9.5M they are best I can tell. I would return these for a size  10M had I not wore them that half dozen times.
