Comments: I know where you're coming from, Bill. When they say the toe box is low, they mean its really low, so that takes some adjustment especially since my other shoes are NB 1400s, which are pretty forgiving in the toe box, but in my opinion aren't as responsive as the Lunaracers. Other than that, they don't have a heel cup, which is awesome, except I've found myself swimming around in the heel area since there's a lot of space I had to relace them after my first couple runs to accommodate that. I never wore the original lunaracers so I can't compare them, but I've heard that the 3's are a touch wider than the originals, and I wear them sockless which I heard you couldn't do with the originals because of an uncovered seam. I've only had them a week, but I've put 70 miles on them in that week, and will try to hit anywhere from 70-90 this summer. So far they hold up well, but time will tell.

Comments: Out of the box I noticed a significant improvement with the material in the upper. The first version was a great shoe but the material in the upper could be pretty brutal. The knit in this version is more comfortable and breathable. The midsole is exactly the same as the LR 1. After a day of walking around I decided to do my 20 mile run in them. They are the same shoe performance-wise. Great cushion and response. Still get the funny sensation at the end of my toes in the latter stages of the run and got a minor blister on a pinky toe. Otherwise no problems. No unexpected knee or hip soreness. Great upgrade by Nike and will definitely run my next marathon in this one.
