Transverse stability bars prevent overpronation without rigid constraints

The training shoe for fast intervals. With Helion? HF hyper foam and a nylon-blend Speedboard? for high energy return.

Helion? HF powers this lightweight running shoe for big energy return. Ideal for fast runs and intervals, it features an ultra-responsive midsole, rockered geometry, and nylon-blend Speedboard? for a fast, forward-rolling ride.

Geometric reinforcement patterns optimize structural support with minimal weight penalty.
