FootFree insoles

This ultrathin two-millimeter insole helps to strengthen muscles on the soles of the feet and fix one's posture.

FootFree is a thin high-quality shape-memory insole born from an idea.

I did not learn about the body until I was over 39 years old. I changed jobs and joined a company that manufactures and sells custom-made insoles. While traveling around the country doing marketing, I was surprised to find that many people were suffering from symptoms such as knee and hip pain and difficulty walking due to bunions. They went to hospitals but could not find relief for their pain. Doctors told them that the cause was aging and the only solution was to build up their muscles. These people found relief with custom-made insoles, which helped them to solve their long-standing problems.

I had conversations with many people who purchased custom-made insoles, many of whom were in their late 60s to 80s. I realized that most knee and back pain was caused by muscle deterioration due to aging. If people started wearing insoles at an earlier age, they would not have to experience this pain and would be more active. However, at the time, custom-made insoles were hard and thick, and could not be easily put in fashionable shoes worn by younger people. This is when I became determined to create insoles that could be worn with fashionable shoes, and I began developing FootFree.

Muscles protect our bodies, and the sole of the foot also has an arch structure supported by muscles. When the muscles in the soles of the feet weaken, the arch collapses, making it difficult to support the body. We have developed a core material that provides moderate elasticity to the entire sole and helps create the muscle movement needed to revive the arch. This moderate elasticity moves the muscles of the sole evenly on both sides, so the hardened muscles relax, and eventually the muscles build up over time. The even distribution of foot pressure enables the body axis to be aligned and the muscles of the whole body to be used in a well-balanced manner. Additionally, the product is offered in half-sizes and is ultrathin at two millimeters, making it great for use with fashionable shoes. This level of thinness was achieved through the skilled craftsmanship of our team. These insoles come in five sizes from 22.0 to 28.0 centimeters for both men and women.

Unmatched Elasticity

The moderate elasticity, which is neither too soft nor too hard, relaxes and conditions the unevenly stiffened muscles in the sole of the foot. This leads to an even distribution of foot pressure that creates better posture and balanced use of the muscles in the body.

The insoles are soft and comfortable, and gently lift the arch structure of the foot as you walk, supporting the muscles of the sole of the foot without strain. The arch structure is maintained even after the shoes are taken off, allowing the wearer to maintain a beautiful posture for a certain period of time.

The core material, which is composed of a unique blend of plastic and nylon. The support offered by this material supports and lifts the arch, leading to a more graceful and confident gait, even when wearing high heels.

Comfortable in any shoe

Ultrathin for Comfort

Typically, more than 90 percent of people view insoles as cushioning materials, while the remaining few percent imagine insoles that support the arch. FootFree is an insole that is neither cushioning nor supportive, but rather an insole that supports a beautiful gait by adjusting the foot muscles. The ultrathin two-millimeter core material is carefully cut individually by skilled craftsmen. It provides unencumbered comfort in any type of footwear, such as sneakers, business shoes, boots, and indoor shoes. Even when worn in high heels, they allow for a brisk stride with a beautiful posture and support the feet when standing for long periods of time.

Highly Regarded by Healthcare Professionals

Our product has been demonstrated and sold at corporate exhibitions, medical conferences, and academic meetings. It has received high praise from doctors, nurses, dentists, and pharmacists, who were surprised by its effectiveness. Below are some reviews from people who used FootFree:
"I feel lighter and more comfortable when I get home."
"I think they are good for stimulating the muscle groups on the soles of the feet on a daily basis."
"I like the fact that the indentation in the heel holds my foot in place so that it doesn't move back and forth in the shoe. I also like the feeling of walking on all five toes. Even though they are only two millimeters thick, when I put FootFree in my shoes I feel as if I am using various muscles, including my glutes, which is quite incredible."
