Abstract
A shoe insole-midsole device configured to fit the profile of the human foot with a distinctive toe end and a distinctive heel. The midfoot section of the insole/midsole device is characterized by an asymmetrical domed structure that is presented to the plantar aspect of the foot at a location found to be the anatomical apex of the foot's arch system. The domed structure displays physical properties such as to catalyze muscle group balancing by utilizing the body's proprioceptive feedback mechanisms. The net result will be a more structurally sound foot capable of more energy efficient and less injury inducing use. In addition to the predominant dome characteristic, the insole/midsole is also typified by a posterior most skiving which reduces impact velocity, thus easing the introduction of the dome characteristic to the plantar aspect of the foot.
