The PR1 Insoles help you develop a controlled midfoot strike.

Land too hard on your heel and the PR1 will provide an auditory cue (real-time auditory feedback) so you can adjust and maintain consistent form.

Improve control over how you move, for better running efficiency while reducing impact on the body. 

Use during practice, competition or rehab for motor learning under real-world conditions.  

No apps or batteries required. Simply trim to fit. 

Weight: 28g per insole (untrimmed)

Drop: 0mm

Stack height: 2.5mm

Surface: Microsuede for improved grip

Foam: EVA
