I have a pretty narrow foot, but the upper on the LR and LR 2 both felt too tight around the toes for my tastes. The original LR used a really stiff material to reinforce the toebox mesh, and i found that to give me all sorts of trouble. The heel area was also a little snug.
The LR2 fixed the width, but it was much too shallow in the toebox, I could barely lift my toes off the bottom of the shoe and I hated it. Much nicer upper material though.
Take the midsole and upper material from the LR2, and build it around the last of the original LR.
