For the best fit, we recommend your usual size if you prefer a snug running feel, while runners between sizes or wanting a little more room through the forefoot may prefer going up half a size. Best For Best for daily training, easy to moderate road miles, treadmill workouts, walking, and versatile everyday wear. Cushioning & Road Feel Runners consistently describe the ride as lightweight, cushioned, and energetic, with enough bounce for pickups while staying comfortable on easy miles. The underfoot feel lands in a balanced zone, soft enough for longer wear yet stable enough to keep transitions feeling smooth on pavement. Break-In & Durability Comfort comes quickly for most wearers, and some note the foam and upper feel even better after a few runs as the shoe settles in.
