FAQs

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.

The position of the heel assembly can affect the sensitivity of the spring. Every shoe and foot combo is different. The goal is to position the spring underneath the back of your heel.

You should be able to roll back on your heels and activate the spring.

A good starting position for the insole is flat across the midsole of the shoe and as far back towards the shoe's heel counter as possible. 

Moving the insole backward and positioning the spring assembly against the heel counter can increase sensitivity.

It depends on the design of the stock insole.

The PR1 should lay relatively flat and as far back towards the heel counter as possible, as shown below:

If the stock insole has a deep heel cup, it can affect the angle and position of the spring. This tends to increase the sensitivity of the spring (which some people prefer). 

If your stock insole is thin enough to allow you to still activate the spring, you can try positioning the PR1 underneath the stock insole but the auditory feedback will be reduced. 

To confirm that the PR1 is positioned properly, you should be able to rock back on your heel and trigger the spring. If you are unable to generate feedback with this motion, the switch needs to move further back towards the heel counter. 

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).

The PR1 main goal is to position the sensor underneath the back of your heel. As the size of a shoe's heel cavity barely increases with shoe size, we are able to cover most Women's 6 - 15 and Men's 5 - 14 US sizes with a single insole template. 

Arch support is not necessary for all foot types and every foot has a unique arch shape. The PR1's minimal design allows a user to fit the PR1 on top of a custom orthotic or insole with arch support.
