From the Research
Orthotics should typically be replaced every 1-2 years for most adults with normal use, as recommended by the most recent and highest quality study available 1. However, this timeline can vary based on several factors.
- Children may need replacements more frequently, approximately every 6-12 months, due to foot growth.
- Athletes or individuals who are very active might need to replace their orthotics annually due to increased wear and tear. The material of the orthotic also affects longevity—soft materials wear out faster than rigid ones. Signs that indicate replacement is needed include:
- Visible damage like cracks or tears
- Decreased comfort or support
- Worsening of original symptoms
- Visible compression of the orthotic material Regular inspection of your orthotics is important to ensure they continue providing proper support. The reason for this replacement schedule is that orthotics gradually lose their supportive properties as the materials compress and break down with use, reducing their effectiveness in correcting biomechanical issues and providing symptom relief, as noted in a study on the orthotic approach to prevention and management of diabetic foot 1. Additionally, a narrative review on the orthotic approach to prevention and management of diabetic foot provides guidance on the use of shoe modifications and orthoses to reduce pressure on the affected foot or provide increased stability 1. It is essential to consider the individual's specific needs and circumstances when determining the replacement schedule for orthotics, as highlighted in various studies on the topic 2, 3, 4, 5.
