KNOW YOUR TECH breaks down the scientific technology used in your favorite sneakers and activewear. Let’s demystify your next purchase: today’s technology is Brooks Ballistic Rock Shield. This thermoplastic sheath between the midsole and outsole is implemented into some of the brand's trail running options for a tough, protective layer which helps to soften the blow of loose objects.
What is it? A ballistic thermoplastic sheath used in the forefoot area to disperse the pressure of landing on rocks, branches, and other potentially hazardous objects on unpredictable trail terrains. Designed to reduce point load pressure yet remain flexible, Ballistic Rock Shield won't slow you down with unneeded bulk.
How does it work? With standard sole setups, the impact of sharp objects is channeled into one point and direction, resulting in an almost uncushioned feel. With Ballistic Rock Shield, the energy of the impact is dispersed over a larger area, which causes the forefoot less agitation during intense trail runs where you may not be able to gauge and avoid the objects you're coming in contact with.

Bottom line: If trails are your preferred terrain, protecting your feet is one of the most important precautions you can take. Brooks Ballistic Rock Shield is a great trail-ready option.
