I received these shoes from Merrell as a replacement for another type that was defective. I truly do not like these shoes. They fit much looser than my other ones. They provide no arch support and actually encourage over pronation as the inside foot bed is lower than the outside. The turning in and lack of support pushes the foot against the plastic stabilizer which begins to really hurt after a very little time.My inserts which fit fine in my last pair do not fit at all in these as the insole cannot be removed. On top of it all the shoes are swampy in that they do not breathe at all. Add to the fact that they slip on wet wood and rock I would not hike in these at all.
