25 cm to 26.5 cm This posture correction insole demonstrates a deep understanding of human health combined with technological innovation. The design concept of this posture correction insole aims to correct posture, reduce physical burden, and even achieve "diet" effects by adjusting the distribution of force in the foot and improving the overall "balance" of the body. Unlike conventional insoles, it not only provides a comfortable fit but also aims to improve the user's overall posture and physical condition from the feet up through scientific support and posture correction. This philosophy of "thinking about health from the feet up" is a significant evolution in the existing insole market and a new exploration in the field of postural health. 【From Floating Toe Improvement to Beautiful Legs, Starting Now!】 "Floating toe" refers to a condition where the toes do not touch the ground or the sole of the shoe when walking, and cannot grip firmly. According to research, over 90% of people, regardless of gender, are likely to have floating toes. If this condition continues, it increases the risk of not only foot fatigue but also various physical ailments and postural problems, such as bunions, strain on the knees and lower back, and even a hunched back. To fundamentally solve these problems, we offer a uniquely developed posture support insole. Its main feature is the "floating toe cushion," which is placed in the forefoot area. By wearing this insole, the entire instep is lifted, allowing all five toes to grip the ground firmly. This allows the body to transmit force correctly from the feet, which can be expected to reduce fatigue and improve foot stability. Furthermore, by allowing the toes to move in the correct position, muscles in the feet that are not usually used are activated, which can also be expected to improve fat metabolism and fat burning effects!! In addition, this beautiful posture support insole naturally straightens the back and improves posture by adjusting the balance of the feet, allowing you to aim for beautiful posture and beautiful legs without strain in your daily life. 【Careful design is applied to each part for the best fit!】 Except for the raised part of the "floating toe cushion" in the "forefoot" area, the other parts adopt an ultra-thin design of only 3mm, making it suitable for all types of shoes. In the "center" of the insole, an arch support structure is specially designed to prevent and improve flat feet. It firmly supports the arch of the foot and reduces discomfort and fatigue caused by flat feet.
