## Overview

The j1 Insoles for Flat Feet are a patented, clinically proven solution designed to alleviate discomfort associated with various foot conditions. With a slim design and a 3-point support system, these insoles are crafted from medical-grade materials and developed by a seasoned podiatrist, making them a reliable choice for adults seeking comfort and support.

## Description

Our clinically proven j1 insoles are a patented 3-point design providing true support, not just cushion for flat feet. They were developed by Dr. Lorri Riley, a podiatrist for over 20 yrs. The patented j1 insoles for flat feet are designed for people with flexible flat feet to bring your arch back up to its neutral position while correcting the foot in all 3 areas: the heel, arch and forefoot. J1 insoles are made of a semi-rigid medical grade plastic much like the plastic used for prescription orthotics. This material allows for the natural shock absorption and flexion of the foot. J1 Slims are medical-grade shells without the top covers, and are designed to slip beneath the insole that came with your shoe. J1 slims are perfect for runners or people wearing dress shoes who want a strong insole without the added bulk of traditional insoles. J1 insoles are made in USA.

## Features

- Indicated for Plantar Fasciitis, Flat Feet, Arch/Heel Pain, Shin Splints, Neuroma, Bunions, Hammertoes, Knee/Hip Pain
- 3-point design for flat feet to provide maximum support
- Medical grade semi-rigid plastic shell
- Developed by Podiatrist with 20+ years experience
- Clinically Proven - PATENTED!

    Very good product. Really works well.
  

*by K***P on Reviewed in the United States on February 11, 2023*

I use both powerstep and J1 Insoles. I am more inclined towards J1 though. Both work fine. It is just a preference. J1 seems a better quality. Powerstep over a period of time peeled off the top layer and seems to wear out a bit faster. Great product. Have one for all of my shoes - work, leisure and sports (particularly for walking and running).
