"So first impressions, these have the potential to be my new favorite shoes (currently my favorite shoes are the Vapor 9s). Out of the box they were much more comfortable than the Courtballistec 4.3. Almost on par with the Vapor 9 when it came to comfort. The other thing was that they are extremely light. They feel lighter than the Vapor 9s, even though the specs say they're .6 ounces heavier. One thing that I noticed is that the toebox was a bit larger than the Vapor 9s and the previous Courtballistecs. I thought it might annoy me, but I was able to cinch up the laces and the Adaptive Fit took care of it. On the court, I thought they were as comfortable as the Vapor 9s, but with much more support. The heel is slightly higher off the court than the Vapor 9s, but the toe box felt the same. I liked that because I could actually "feel" the court much more than I could with the previous CBs and the Air Max Cages. One of the other things that I noticed is that they were much more "springy" than the Vapor 9s. It might be the Lunar cushioning system. With the Vapors I feel like I somewhat "sink" whenever my foot hits which I like since it cushions the blow, but with the Lunar Ballistecs, I felt like it had a slight trampoline effect when I landed. I kind of liked that too. It cushioned my blow, but it felt like my first step was much quicker. One thing that might be an issue in the summer is that there doesn't seem to be much ventilation. All in all, I think I will really like them. I've been looking for a sturdier shoe that was still light like the Vapor, and this fits the bill. Plus, it has a 6 month outsole durability guarantee so it should last me much longer than my Vapors."
