With nearly 150 illustrations, this book clearly illustrates the foot structure from newborn babies to young adults, its mechanics, and how our body stands on the foot. Our leg stands right on the anklebone, which is a part of the tarsal joint, a group of joint that forms the arch of the foot. This tarsal joint needs orthotics from under the arch in order to keep the joint from disengaging. If there is no support under the arch, this tarsal joint disengages with each step kids make throughout the day. This disengages the tarsal joint, and tilts the anklebones instantly; this deforms the foot shape, and misaligns the entire body structure. Therefore, our kids are growing without the alignment from the feet up; this causes many structural problems throughout the body, such as bow-legs, knock-knees, scoliosis, and etc. It's imperative to keep the tarsal joint from disengaging with the orthotics under the arch area that align the anklebones; this provides the foot with balance and comfort, and the entire body structure can grow with alignment from the feet up.
