The official name of the shoe is Nike Air Zoom Vapor X Knit. So here's my initial review of the shoe, but as you all know this is completely subjective, but in my honest opinion these are the best Tennis shoes I've have ever owned! To start, I get all my tennis shoe's true to size, size 9 and always double sock. With these shoes when I initially tried them on I was a bit concerned because they felt a little tight in the forefoot. I would say I have a little bit of a wider foot than normal, but do not be concerned this does not cause problems, it seems that the flykit stretches a bit, or this is how a true lockdown should feel. The shoe I believe uses the Nike Air Zoom Zero one piece tongue, heel boot/sleeve that you side your foot into separate from the shoe. You then add that with the flykit that wraps around the shoe, and it creates a lockdown I have never felt before and in my opinion the best. My feet in no way were sliding in any direction within the shoe and caused no foot pain. I could sprint, slide, and move laterally, with my foot being completely locked down. I usually have problems with stubbing toes, but not with this shoe. The only down side I could see is the breathability. The Flyknit is thick and with the two piece construction with the sleeve insert, I could see breathability being an issue. The tread pattern of the sole and Nike Zoom is exactly the same as the Vapor X, so expect normal wear. The look of the shoe is awesome IMO. Comparing the different Nike shoe's I listed above, I would say it fits more along the lines of a Cage 3/Zoom Zero, but still has the play feel/ride of a Vapor X. As I stated above, I believe Nike really nailed it with this shoe and is definitely worth the $30 more than regular Vapor X.
