When your running calendar shows that it's team for speedy track repeats or interval road runs, you'll want to turn to the quick and responsive performance of the Salomon Sonic RA Pro 2 Running Shoe. Not only is this shoe the lightest in Salomon's RA road running lineup, but it's also got a few tricks up its sleeve to help you hammer out quicker times. Its cushioned midsole works to not only absorb vibrations that might cause muscle fatigue and joint discomfort, but also ensures a responsive ride to keep some energy in your stride when you feel tempted to lay off the pace. This shoe also features Salomon's Geometric Decoupling technology, which essentially splits the midsole vertically down the middle, allowing the shoe to more naturally roll with your foot through its gait. The result is a more efficient, healthier, and comfortable stride that'll keep you moving quickly on training runs and race days.
