I like these a lot.  I'd give them five stars if the color selection wasn't so awful.  I checked the Brooks website, and it seems that terrible colors are a Brooks problem rather than an Amazon availability problem.  These fit well enough for me, but I'll probably go half a size up if I buy another pair from this brand.  I have a medium to narrow foot, usually 8.5M in dress shoes and 9M in running shoes.  I got a size 9 in these and they fit, but my toe is kind of close to the front of the shoe.  They're soft on my knees, and they have a nice rolling forward feeling as I'm running, if that makes any sense.  I'm an on-and-off beginner runner, and I was hoping for a comfortable shoe that will protect me from the road a bit.  These seem to do the trick.
