I just started running consistently this last year, so I don't have a lot of experience with running shoes.  I do have an indoor pair of Nike Frees which I like, but for outdoors, I use the Montrail Rockridge trail shoes.  In my opinion, the Rockridge trail shoes are more comfortable than the Nike Frees, but they are slightly heavier and the bottom has rubber, which makes the Rockridge shoes harder.  However, the whole reason I bought these is because outdoor terrain is less forgiving than an indoor/outdoor track.  These shoes feel comfortable on grass, gravel, and anything not paved/cemented.  When I run on cement they feel a little stiff, but I prefer to run on the earth next to the sidewalk.  These shoes are designed for trails, and from what I can tell, they hold up well.  I would recommend these shoes to anyone who is looking for an outdoor trail running shoe.  I gave a 5-star review because they are excellent for what they are designed for.  I would not buy these for running on cement/pavement, but like I said, they are designed as trail shoes.

I'm a size 10 and ordered a size 10 which fit great.  I usually don't order shoes online because I don't know how they will fit.  But this really worked out.  I can't wear shoes that have a high arch.  Thankfully, these do not.
