BETA ON THE TRAIL Z2The Vimazi Trail Z2 is designed and engineered for running from road to trail, with an emphasis on steep and rugged. With an aggressive tread, external rear stabilizer, stump-ready toe protection, and built-in forefoot control during push-off, there is no compromise on cushioning or control. All other brands give you one or the other, not both together. WHO IT'S FOR Tackling steep and rocky terrain? You'll always want to grab the Z2. The firmer FastPod keeps you surefooted on the steepest descents. The impact absorbing heel makes for a smooth transition on flat terrain and roads.
