share, Brooks revenue hit $500 million. Weber stated that based on the company's year-over-year growth, investments from Berkshire Hathaway and the support of its CEO, Warren Buffett, Brooks would become a billion dollar brand. The Brooks Heritage Collection was launched in 2016, returning the Vanguard, the Chariot, and the Beast to the market. Only the technology was updated; the details of the original shoes, including the colorways, were replicated. Brooks introduced the first customized performance running shoe based on personal biomechanics in the United States in December 2017. An in-store station that combines 3D foot scanning with gait analysis and pressure mapping, it was developed in partnership with HP and Superfeet. In 2017, Brooks shoes were named Best Running Shoe (The Glycerine and the Launch, Sports Illustrated); Editor's Top Choice (The Adrenaline GTS 18, Runner's World); and Ten Best Running Shoes (The Levitate, Men's Fitness). Shortly after, Brooks developed the DNA Flash—their first nitrogen-injected midsole technology—and applied it to silhouettes such as the Hyperion Tempo as well as a few easy everyday running shoes. The brand worked with nitrogen injection for about three and a half years before releasing its DNA Loft V3 nitrogen-injected foam, which was introduced in the Aurora BL sneaker. Sustainability and social responsibility Brooks Running has implemented environmentally conscious practices into their business and manufacturing practices. Several models of their shoes have High Performance Rubber Green (HPR Green) outsoles that are made with sand instead of petroleum. The company says that it uses recycled materials to make other parts of their shoes "whenever possible", including laces, fabrics, hangtags and packaging. In 2014, the company partnered with Bluesign Technologies (stylized as bluesign technologies) to evaluate, manage, and eliminate priority chemicals used in the process of manufacturing apparel. Manufacturers that become Bluesign system partners are required to establish management systems for improving resource productivity, consumer safety, water emissions, air emissions, and occupational health and safety. Brooks is also a member of the Sustainable Apparel Coalition, a global trade organization that works to reduce the environmental and social impact of apparel and footwear products. With the some collections, Brooks offers vegan products. Built in 2014, the Brooks headquarters meet the environmental standards of Seattle's Deep Green Pilot Program. The building captures and reuses at least 50 percent of storm water on the site and uses 75 percent less energy than a typical commercial building in the city. As of
