I did a little mini review on my experience in the M7. It is actually in my Jordan 2011 post.
Taken from my original post:
For the M7 I was gonna do a separate review, but I'll give you mine here.
First Impression: It seems JB is making an effort at quality. In person (I had the jades) there is a lot of minor details that you don't see in pictures. The materials seem quality. I was pumped about this shoe after seeing that it has zoom in the forefoot and air in the heel. I was ready for a performance beast.
The height of the ride reminded me of the xii's. The M7 felt like old jordans used to. Not super high off the ground, but slightly elevated. I'm not a huge fan of the low to the ground feel all the time.
Fit: The shoe fits snug. Very snug. It will lock your foot down and for me it was the shoes downfall and biggest benefit. The shoes comes out of the box extremely stiff. It definitely needs to be broken in. It hugs your heel extremely hard. You have to wear crew socks with them. Anything lower will have the back part digging at your heel. Not as bad as the 2009,2010, KDII, but it was an issue for me. After that I liked the shoe a lot.
Once broken in the cushioning and the rest of the shoe is great. Although I would recommend it more for big men. I loved it in the post. Every step felt like it was with a purpose and if your a big man who has good footwork these make you feel like Michael Jackson in Billie Jean. Like every part of the floor lights up when you put down a step. You feel powerful and ready to move the next one. You are definitely aware where your feet are in this shoe.
For guards this may be too stiff and stable as many guards and slasher like a little give or a lower cut.
