THIS SHOE IS FOR: The Levitate 4 is perfect for runners who want a shoe that helps them by giving energy back with each step, the Levitate 4's DNA AMP is now 20% lighter so our highest energy return foam is better than ever. ENERGIZED CUSHIONING: Now 20% lighter, our DNA AMP midsole technology lets your foot spring off the ground with each step for speedy, efficient energy return. SECURE, SOCK-LIFE FIT: We updated the Fit Knit Upper to provide a close-to-foot fit that’s lighter, softer, and more breathable than before. The Levitate 4 runs more shallow and provides a slightly more snug fit. If looking for a more roomy fit, Brooks recommends sizing up by 1/2 a size.
