Foot SoldierFoot Soldier History

The Foot Soldier products were some of the first over-the-counter foot orthotics introduced to the orthopedic market. Developed by KLM Labs in the early 1990s, the Foot Soldier Shells were the first of their kind. All foot orthotics existing in the market up until that point had been custom made to the molds of patients' feet. As one of the leading manufacturers of custom foot orthotics in the United States, KLM Labs had the opportunity to study thousands of patients' casts, and their resulting foot orthotics. By using 3D imaging software to analyze these shapes, KLM determined the average foot orthotic by shoe size. These Foot Soldier shapes were made into injection molds so the orthotic shells could be manufactured at a lower cost, resulting in a more affordable price for the end user.

The Analysis

Further study of over 133,000 pairs of orthotics shows that certain foot shapes exist more often than others. Of the thousands of shapes that were documented, 99 shapes occurred 70% of the time. These shapes became the System Rx Products. Click here to read more about KLM's System Rx Technology. Most feet fall into a relatively small range of measurable dimensions. By mathematizing these shapes and sizes of the feet, KLM Labs made the art of biomechanics more accessible to the general public. KLM's goal is to make the best foot care available to as many people as possible.


Foot Soldier Products are the orthotic shells and insoles designed to be useful and affordable to as many people as possible. Simply order by shoe size with an additional choice between three levels of support. KLM Labs supplies Foot Soldier Insoles to Veteran's Associations nationwide. KLM is proud to provide orthotics to our nation's heroes, and that does not exclude the working people who make our country what it is, day in and day out.

Foot Soldier Products

Foot Soldier Products include the Foot Soldier Shells, Foot Soldier Insoles, and Foot Soldier Plus Insoles.  All of these products use the Foot Soldier Shell as their orthotic base.  This shell is defined by KLM Labs as the average custom foot orthotic by shoe size.  While some individuals truly need custom arch supports, most people have relatively normal feet.  This does not exclude them from experiencing foot fatigue, plantar fasciitis, heel spurs, bunions, and the many other common foot ailments that occur due to excessive daily use and improper footwear.  Foot Soldier Products come in three levels of support: mild, medium, and max, so you can adjust the strength of the orthotic to your personal weight and preference.  KLM Labs is proud to provide Foot Soldier Products to the United States Military, as well as countless Americans just like yourself.
