Introducing new, groundbreaking Brooks DNA, a run-changing innovation made possible by “Brooks Genetic Engineering.” No, we can’t clone you or grow you a faster set of legs in the lab. This is better: an innovative cushioning material that responds to the unique differences that make each of us who we are as runners. So you, as you are, can run at your best. Making its debut in the stellar Glycerin® 8, Brooks DNA consists of individual molecules connected in strands and chains that react to the amount of force placed on the foot. Combined with BioMoGo, Brooks DNA disperses pressure and provides the optimal level of cushioning for your individual weight, pace, biomechanics, and running environment. That’s right. Brooks DNA does the seemingly impossible by providing a level of cushioning that is tailored to your own unique, changing needs. This is huge. And scientifically speaking, it’s a lot more fun than letting your clone run the back half.
