Plantar fasciitis is inflammation and pain in the heel. This is usually considered to be a repetitive strain injury. Repeated micro-trauma to the plantar fascia causes inflammation and pain. The worst pain is usually early in the morning on the first step. It affects both runners and also those who do not regularly engage in strenuous physical activity. There is a lot of evidence to suggest that orthotics help to reduce the pain in plantar fasciitis. References 1 to 3 provide further reading material regarding how orthotics help with plantar fasciitis.

- A systematic review conducted by Lewis and colleagues revealed that, within 1 to 3 months orthotics can improve the pain levels and functionality for individuals with plantar fasciitis

- Whittaker, et al, studied a comparison between steroid injections and orthotics and concluded that, whilst steroid injections provided temporary relief, orthotics provided a more sustainable and longer term benefit.
