Disclosed herein are insoles useful for treating skin injuries on a foot, for instance ulcers. The insoles are customizable for each patient's foot and can include various portions of differing softness, depending on the needs of the patient. For instance, it can be beneficial for certain sections of the foot to contact a firmer material, whereas other sections contact a softer material. Some, or all, of the materials can include one or more biofidelic skin simulant materials. Thus, various implementations include one or more regions that can include the same or different materials. For example, a custom insole can include a heel support region, a midfoot support region, and a forefoot support region, and the support regions can be subdivided into medial and lateral support regions or toe regions. One or more regions may have a custom isolation segment to prevent the progression of ulcers and/or expedite wound healing.
An insole having a support layer, the support layer comprising one or more support regions, each support region comprising a support material simulating biomechanical properties of human skin, the support material comprising an elastomeric network having an elasticity modulus low stretch ratio from 2-8 MPa and an elasticity modulus high stretch ratio from 6-90 MPa, wherein the elasticity modulus high stretch ratio is greater than the elasticity modulus low stretch ratio.
