The reviews are correct you DEFINATELY have to break these in.  They are slightly heavy, and soles are hard.  I wore them on rocky ground and they did not fail me. They worked well for rough terrain.  I think once I wear them more I will love them.  The size is slightly on the small size.  I usally wear an 8 but ordered these in a 9 and they work perfect.  Adjusting the straps is key when you first get them.  Would recommend.
