What are Vionic insoles made of and how long will they last?

Vionic insoles and sandals are made of a flexible material called EVA (ethyl vinyl acetate).
The key advantage of EVA is that it is supportive and 'giving' at the same time! As you apply weight to the foot, there is a certain amount of 'give' in Vionic insoles and sandals, providing shock absorption to the feet, ankles, knees, hips and back. This makes the device much more comfortable and more natural compared to hard insoles. Yet, at the same time, they are firm enough to realign the foot and allow you to claim back your natural footprint.
Because Vionic insoles and sandals are somewhat flexible, they will need to be replaced every 12-18 months. Older people or those with sensitive feet will benefit from a softer type of orthotic such as Vionic, as they may have difficulty tolerating anything hard under the foot.
