Carbon fiber insoles (VKTRY, Milford, CT, USA) were initially designed to increase ground forces leading to a harder push off for faster running or higher jumping. To enable energy return, the insoles require extreme rigidity and therefore are composed of a full-length carbon-fiber base. The highly rigid construct of the carbon fiber can potentially benefit patients with plantar fasciitis by using these insoles in their own shoes, which could lead to more effective pain management, increased compliance, and improved patient outcomes. While this insole is currently being widely used by athletes, the application of this insole for PF patients has not been explored. Therefore, the aim of this study is to understand how patients respond to the these insoles compared to current standard orthotics (Superfeet Green, Superfeet Worldwide LLC. WA, USA and Aetrex L20, Aetrex Inc, NJ, USA) in a blinded randomized controlled trial.
