The Jet Mach II is a fresh update to Babolat's speedy shoe silo. At first glance, these shoes look and feel nearly identical to the previous Jet model. However, this update features a new Matryx 2.0 upper material, which weaves kevlar and polyamide threads together for even higher levels of comfort, support and durability. These ultra-light shoes absorb harsh court shock and lock in your feet for complete confidence. Three of our four playtesters have worn Jets in the past, and they were excited to see what sets the Mach II apart from its predecessor. When our team tried on the Jet Mach IIs they found that they run short, and that going up a half or a full size would be necessary. . When it came to durability, the Jet Mach IIs held up to our testers' expectations, especially considering how light they are. All in all, the Babolat Jet Mach IIs are great match-ready shoes for all levels of players, as long as you size up.
