If I was a pro tennis player, these shoes would be perfect because I would have the ability to play every match with a brand new pair. Unfortunately, I'm not and these tennis shoes are extremely lacking in the durability column. They are fairly comfortable and provide above average support but I have now gone through 2 pairs in less than 8 weeks. The loss of traction is felt nearly immediately within the first 1-2 weeks of playing. Pretty disappointing considering it's on the high end of the market.

This shoe has many pros and one con. One. So the good about the shoe is the traction, the looks, the cushioning is decent, and the fit and ventilation are great along with support. The one thing that is meh is the lack of foam in general. Now the one downside is the durability of the outsole. While it is nowhere near as bad as the vapor 9.5, it still starts wearing down quickly. With the next model, Nike, please make the rubber much more durable and put a little more foam in the forefoot and heel.

I liked the Zoom Vapor 9.5 fine, but I like everything about the X more. Fits great (same size for all my Nikes), feels fantastic (super light and comfortable), looks better than anything else, and lasts a lot longer than I expected (months longer than my 9.5's and easily as long as my Cage 3's when playing 3 times/week). I'll be stocking up on favorite colors because I don't expect any challengers for a while. This could be a classic.
