The CEP Pro Run Optaspeed Bowtech takes longer efforts and uptempo workouts to the next level with higher levels of energy return and a focus on performance training

Tackle Everything From Uptempo Runs to Race Day in CEP’s Performance-Driven Trainer

The CEP Optaspeed is built to deliver speed, momentum, and control, no matter the type of workout or effort. With lots of energy return and a dynamic running experience, this performance-focused trainer will drive you through each stride in comfort and confidence.

The Optaspeed incorporates lots of innovative technology, most notably the patented BowTech Kinetic technology. The unique dual PEBA plates flex and store energy with every foot strike. As you toe off, the plates release this energy, helping you accelerate and propel yourself with more momentum through your stride.

This one-of-a-kind plate design is paired with a responsive dual-density midsole for even more dynamic comfort. The EVA foam in the heel effectively absorbs shock, while the more explosive N+ foam in the midsole creates more speed as you push off the toes.

The monomesh upper is lightweight and well-ventilated for maximum breathability. And while the upper itself is thin and flexible, the innovative foot cage and durable toe cap adds extra protection and support. Finally, you can enjoy all these features for longer due to the durable rubber outsole designed to last nearly 500 miles.
