The j1 Difference

  • Many over-the-counter arch supports claim to be for flat feet, and even some prescription orthotics are supposedly made for flat feet. But j1 Insoles really are for flat feet. The major difference? j1's are based on a patented 3-point design for flat feet.
  • j1 Insoles are made of a medical grade plastic like what is used in prescription orthotics, while most over-the-counter supports are made of mere foam and provide little or no support.
  • j1 Insoles are designed to run the entire length of the arch - from the heel to the metatarsal heads. Most arch supports, including prescription brands, end right behind the metatarsal heads. By ending too short, these insoles dig into the metatarsal heads area, which can be very painful. At j1 we know that the arch, like a bridge over a river, must be supported fully, or it will collapse.
  • Our j1 Juniors start at toddler size 4 and go all the way to children's size 4. We have them for high/average arches and for flat feet!
  • j1 Insoles were designed by a podiatrist who has flat feet and wears the insoles herself.
  • j1 Insoles vs. ankle braces for pronation: Ankle braces only support the ankle, so the foot still continues to pronate. The ankle braces are bulky and hard to fit into shoes. They also don't go all the way to the metatarsals, where they are needed.

EXTREMELY DURABLE

The medical-grade shell is made of the same durable plastic used in prescription orthotics, but it’s semi-flexible to allow the foot its natural motion. The closed-cell EVA top cover withstands moisture, has memory and does not break down easily.
