At StepRelief, our value of Proof means providing functional support tailored to specific needs. Orthotics provide relief for many chronic conditions by redistributing weight, relieving pressure, and providing cushioning. The effect you can expect depends entirely on the material and design of the orthotic inserts you choose.
1. Insoles for Plantar Fasciitis & Alignment Issues
• Plantar Fasciitis: This condition requires stabilization. A functional orthotic arch support should use either a semi-rigid (for flexibility and comfort) or rigid footbed (for aggressive support). Rigid orthotics are useful in treating plantar fasciitis by preventing the arch from collapsing excessively.
• Alignment Issues (Over-Pronation/Supination): If your foot rolls too far inward (overpronation) or outward (supination), a semi-rigid or rigid orthotic arch support combined with a heel cup will help keep the foot aligned. Functional orthotics, often made from hard materials like polypropylene, guide the foot’s movement toward natural pronation.
2. Insoles for Arthritis Pain
People with arthritis require cushioning that reduces joint impact and alleviates stiffness. Comfortable orthotics utilize softer and less rigid materials, such as EVA foam or neoprene, focusing on padding and cushioning a painful or injured area. They minimize the abuse and shock the feet suffer daily.
3. Diabetic Orthotics and Neuropathy Support
For the diabetic at risk foot with peripheral neuropathy, the critical focus is on offloading high plantar pressure to prevent foot ulceration. Highly effective design features proven to reduce peak pressure include:
• Arch Profiles: Adding an arch profile can enhance the offloading effect by increasing contact area and distributing force over a greater area. An arch profile can reduce peak pressure by a mean of 37 kPa compared to a flat insole.
• Metatarsal Additions: The use of a metatarsal pad can reduce mean peak pressure by a further 35.96 kPa when compared to an insole without one.
• Apertures: Insoles can be modified with a cut-out to specifically target and reduce pressure directly under a site of clinical interest.
• Materials: Plastazote foam is often used as a soft, accommodating top cover in the construction of diabetic orthotics.
The material choice is central to the insole's ability to redistribute or dampen forces effectively.
