All of our boots and shoes are true moccasin construction, which consists of a flat foot bed with no cushioned insole along with either one, two, or three layers of leather underneath your feet depending on the style chosen. Due to the moccasin construction of our boots and shoes we are unable to build around orthotics/inserts. A moccasin is meant to mold to your feet, orthotics prevent that from happening. If you need some cushioning in your boots/shoes we have a black poron slip sole that can be added to double and triple vamp boots and shoes, as well as our double moccasin bottom construction. For single vamp boots and shoes, a poron sock lining can be added. Thank you.
