Several materials used in insoles have good shock absorption properties. Some common materials known for their shock-absorbing capabilities include:
1. EVA (Ethylene-vinyl acetate)
This is a lightweight and flexible foam material commonly used in athletic footwear and the construction of insoles. EVA provides excellent cushioning and shock absorption, making it a popular choice for running shoes and insoles.
2. Gel
Gel inserts or gel-based materials are often incorporated into insole designs to provide enhanced shock absorption. The gel absorbs impact forces, dispersing them throughout the footbed and reducing stress on joints.
3. PU (Polyurethane) foam
Polyurethane foam offers great resilience, durability, and shock attenuation properties, making it suitable for absorbing impact during walking or running activities.
4. Memory Foam
Memory foam molds to the shape of your foot when you step on it, providing customized support while also absorbing shocks effectively due to its viscoelastic nature.
5. Poron
Poron is an open-cell polyurethane material that offers exceptional energy absorption capabilities by dissipating impact forces away from sensitive areas like heels or forefoot.
6. Air Cushioning
In some cases, air-filled pockets or chambers are integrated into the design of insoles to provide additional cushioning and absorb shocks upon heel strike or landing during physical activities.
It’s important to note that different combinations of these materials may be used within an insole design to optimize both comfort and shock absorption based on specific needs.
While considering which material is best suited for your requirements, it can be helpful to try out different types of insoles with varying compositions to assess personal preferences regarding comfort level, overall support needed, individual biomechanics as well as any existing foot conditions one might have.
