Row of feetWhy are there two types of j1 Insoles?

For the same reason there are different types of eyeglasses for near-sighted and far-sighted people. There are two basic types of feet - flat feet and high/average arched feet. If you're not sure which kind of arches you have, check out WHICH j1 INSOLE IS RIGHT FOR YOU? Approximately 25% of the population are born with flat feet. However, another 10-15% of the population's arches will fall enough that they will need the correction that j1 Insoles for flat feet provide. If you are not sure, check out this video...

Which is better, 3/4 length or full length?

Both are great - it's all about preference. If you need more space for your toes, we recommend the 3/4 length. However, the 3/4 length insoles have more of a tendency to slip forward, whereas the full length will not. This sliding problem is easily corrected by either putting the insoles under your shoes' inserts, or putting double stick tape or velcro in the heel area.

How do I know I have the right size of j1 Insoles?

The shell (the hard part of the insole) should end in the metatarsal head area - not behind it or at the very end of the metatarsal head. If you have found you have gotten the wrong pair, we will gladly exchange them for you at no cost.

How long do j1 Insoles last?

On average, j1 Insoles last from six months to one year, depending on how much they are used, your activity level, quality of the shoes and your body weight.

How can I tell if my child has flat feet?

Some indications that your child may have flat feet are: toe walking, in-toeing, not wanting to wear shoes, standing/walking on the side of their feet (to compensate), and/or rolling their ankles in.

Feet on beachI only have one flat foot, can I get both types of Insoles in one order?

Will my j1 Insoles fit into my dress shoes?

Majority of j1 Insoles do not - it depends on the makeup of your dress shoe. The j1 Slims would be your best bet to try since they do not have the extra bulk of the top cover.

Why do other generic arch supports hurt my flat feet?

Generally it is because they are not correcting in all essential three points of your foot. j1 Insoles have a patented 3-point system that corrects for flat feet in the heel, arch and forefoot. Most other generic and even some prescription orthotics do not have that, but at best only address the flat arch issue.
