If you want to watch things get vicious, ask a group of runners what the right pace is for a tempo run. Stand back and get ready to hear about heart rate percentages, perception of effort, pace comparisons with every distance from the mile to the marathon, hour runs and 20-minute efforts. What many runners do agree on is that the Tempo 9, among the best Adidas running shoes for men, is perfectly designed for your tempo run workouts. The Tempo 9 is a highly flexible and more supportive equivalent of the Boston 6, with plenty of Boost rubber to keep you bouncing through longer races or faster workouts. If you feel like you’re floating above the ground, effortlessly flying through a workout at a aggressively fast pace that feels too easy, you may have finally figured out the right pace for a tempo run. Or maybe it’s just the Boost rubber in your Tempo 9’s.
