I have not been a big fan of Nike shoes, however, the LunaRacer 3, just recently released interested me and I thought what the heck give it a try. I thought the Brooks Pure Drift was going to be my speed work/fast training shoe, however, no dice on that one. According to the Runners Warehouse this shoe has a 5 mm drop (stack height 25mm heel and 20 forefoot) http://www.runningwarehouse.com/descpageMRS-NLR3M1.html
The toe box appeared to be wider than most Nike racers (the Nike Flyknit racer is very narrow). The toe box is wide for a Nike (almost as wide as the Mizuno Universe 4). I have put 30 miles (including a 9 mile run) on it so far and I really like it. The fit is great due to the flywire technology. It is very comfortable shoe to wear for fast training. The cushioning, Lunarlon, is great not too mushy and not too firm. The upper is a mesh material which is very breathable. This is not a shoe for going slow but built for fast training or speed work. Also the shoe has a removable insole which is a bit unusually for a racing shoe. Weight is light 6.4 oz in a size 9.
