The Fulcrum unit, the shoe's pivot point, sits further forward than on the 4.5. The shift smooths the transition from stance to toe-off, so the strides move forward rather than stalling underfoot. Combined with ample toe spring, the result is a roll that asks less of your legs, stride after stride.

For the runner who covers distance and still wants room to pick up the pace. The Fusion 5.0 holds its cushioning over long runs and stays efficient when the pace drops. One shoe, both kinds of days.

The upper is new throughout. Secure through the midfoot with more space in the toe box for the foot to move naturally. A padded heel counter adds comfort and keeps the heel locked in place. Reflective elements sit on both the medial and lateral sides, for visibility on darker runs.
