The Nike Lunar Ballistec is a futuristic looking shoe with performance-enhancing technology to match. If you’re looking for exceptional comfort and durability, you’ll definitely want to give these shoes a try.

Performance
They may appear bulky, but these lightweight shoes (13.6 ounces for a size 10) are actually quite quick around the court. Their exceptional level of comfort makes it easy to play for hours on end without your feet feeling sore at the end of the day. I definitely had no problems going all day long with these shoes, which I’m sure is no fluke thanks to the lightweight and comfortable design.

Durability
One of the things that I love about how durable these shoes are is the awesome drag guards they have. Even if I wear through them, Nike provides a six-month out-sole warranty – all I have to do is pay for shipping. Of course, it won’t be easy to wear down the XDR Rubber outsole – that stuff is tough!

Comfort
These are definitely some of Nike’s more comfortable shoes that they have produced. With features like Flywire, an adaptive lace system and synthetic leather, these shoes snuggly conform to your foot. With a snug fitting shoe, you want it to be breathable so your feet don't get too sweaty, which is made possible thanks to the mesh upper and perforations on the toe. Further comfort is provided with the Lunarlon mid-sole, which is specifically designed for tennis players to provide lightweight cushioning at the balls and heels to keep you on your toes all match long.

Overall
With the high level of durability and comfort that you get from these shoes it’s no wonder that many top tour players make this their shoe of choice. As long as you don’t find these shoes too bulky, they quickly fall in love with how amazing these shoes are.
