Toe Spacers [Correct Toes] for Hallux Valgus, Flat Feet, Arthritis, Usable During Walking and Running Correct Toes are high-quality toe spacers designed for those suffering from misalignment (deformities) of the toes. They are especially recommended for people whose arches collapse and whose big toes don't spread even when wearing shoes with a wide toe box like Altra. Wear Correct Toes and start walking. At first, you may feel a sense of discomfort, but with practice, your toes will spread, and you can achieve natural toe alignment. They can be molded to fit various foot shapes, so anyone can use them. 【Story】 Dr. Ray McClanahan, who developed Correct Toes, is a "podiatrist," a medical specialty already well-established in the United States, and was originally an elite long-distance runner. He had many problems during his athletic career and addressed them with various approaches. However, he didn't feel that any of them, including orthotics, painkillers, and even surgery, were a complete cure. No matter what treatment he received, he couldn't cure the root cause. So, he changed his thinking from "suppressing symptoms" to "treating the root cause," and that's how he arrived at "Correct Toes." 【Dr. Ray's Realization】 After reading various literature, analyzing the movements of many runners, and learning from the running of barefoot runners, he reached one conclusion: "Natural Toe Spray" (the natural spread of the toes) is the most important factor for maintaining long-term foot health. 【Features of Correct Toes】 As the only toe spacer that can be used inside shoes (shoes with a natural foot shape), it uses medical-grade silicone that can be used during walking and running, is soft, does not injure the toes, and also ensures sufficient strength. It is most effective when weight is placed on the foot, and it is the most reliable toe spacer widely used in medical settings in the United States.
