Sizing is based on user weight

The pressure sensor in the heel is tuned to provide feedback based on the amount of force applied. Lighter athletes, those under 100lbs (45kg), require more sensitive feedback.

Trim to fit - one size fits all

Covers Youth size 1 to Men's  14 & Women's 15. 

The sensor in the heel is the only part of the insole that cannot be cut. The sensor is narrow enough to accommodate shoe sizes down to Youth size 1.

The PR1 uses auditory feedback to help athletes reinforce proper footwork. 

Our patented Stride Detection Sensor (SDS) provides real-time feedback when you place too much weight on your heels. This creates a simple feedback loop that helps you correct and maintain proper form.


The PR1 is easy to incorporate into drills, practice or competition. Take everywhere to build better footwork under every condition.
