The PR1 can be used with most sport-specific footwear (running, soccer, football, baseball, tennis basketball), minimal footwear, or casual shoes. Not recommended in shoes with a heel drop in excess of 15mm (aka shoes with a large heel).
Speed is a skill
Faster athletes have more efficient technique, not outright body speed. In other words, speed is a skill.
How the athlete makes ground contact (footstrike) is the single biggest factor in determining their overall speed and agility.

Don't be caught flat-footed
Keeping weight off your heels allows you to reach quicker as you can produce more force through the balls of your feet.

Run faster
Landing on the ball of your foot (mid foot or forefoot) is faster than landing on your heel as it allows for faster turnover and greater force production.
How the PR1 works
Control your footstrike
The PR1's feedback loop is a simple but powerful way to reinforce proper footwork.

1. Improper footstrike
The athlete places too much pressure on their heels, be it from overstriding, excessive heel strike or standing flat footed.

2. Auditory feedback
The PR1's patented Strike Detection System (SDS) provides real-time feedback, creating a powerful feedback loop.

3. Proper footstrike
The athlete learns to control their footwork in an effort to avoid triggering the feedback from the SDS sensor.
Consistency is key
You're only as good as your last step. The PR1 helps you maintain consistent form.
This graph shows the same athlete running with and without the PR1. The light blue line demonstrates how consistent the athlete's footwork is over time when using the PR1. The dark blue line shows the athlete's form deteriorating with time without the PR1.


Deep motor learning
The PR1 is unique in its ability to help you master your footwork under real-world conditions. Move beyond static drills and develop elite footwork everywhere.

Unconventional design
Conventional insoles focus on treating symptoms of poor form. The PR1 instead is focused improving your underlying mechanics to unlock your athletic potential.

Efficiency
Cushioning reduces efficiency as it slows the transfer of power between your foot and the ground. The PR1 uses 3mm of EVA foam for efficient power transfer.
Mobility
The PR1 is zero drop (constant thickness throughout as opposed to thicker in the heel) so it will not impact the mechanical characteristics of your shoes.
Mobility
Arch support restricts movement in your foot and weakens the foot's muscles in the process. The PR1 allows your foot to move freely with no arch support.
Frequently Asked Questions
What shoes work with the PR1?
How to install
Use your shoe's stock insole as a template to trace onto the PR1.
Using scissors, cut along the outline. Do not cut the hard heel section of the PR1.
Position the PR1 so it lays flat with the logo facing up inside the shoe. The PR1 should be as far back towards the heel of your shoe as possible.
Rock back on heels to check spring activation. It sensitivity and position of activation should feel identical between feet. Adjust PR1s as necessary to get symmetry.
Do I need to remove my shoe's stock insole?
The PR1 is designed to replace your shoe's stock insole. While placing the PR1 on top of your shoe's insole may work, it will limit the sensor's feedback.
Why is there no arch support?
Arch support is not necessary for most athletes. The foot is designed to flex under load and arch support immobilizes the foot.
Arch support should only be used under the guidance of a professional as it will dramatically alter the alignment and range of motion across the entire kinetic chain.
The PR1's thin design allows the user to fit the PR1 on top of a custom orthotic or arch support if necessary.
