The BeastTM is a motion control superhero that comes to the rescue of runners with low or flat arches and excess pronation. It features the industry's most advanced technologies, like Brooks MoGo midsole compound for increased energy return and enhanced cushioning over more miles, plus e-1TM and e-2TM to absorb impact shock and boost resilience. Thermo-regulation is the latest addition to its list of superpowers, thanks to thermo conducting, silver-embedded x-Static® in the sockliner and linings.
