This stretches the plantar fascia. In this case Keravita Pro Review the orthotic must stop the heel from everting (heel rolls in). In this situation we prescribe an orthotic that cups deep around the heel and has a built-in wedge that prevents the heel from rolling in. In other patients suffering from plantar fasciitis and/or heel spurs, the heel stays straight, but the arch collapses - again this lengthens the foot and stretches the fascia.
In this case the orthotic will be prescribed to focus on arch support - a very different function than stopping the heel from turning in. In this case the podiatrist should focus on prescribing an orthotic that conforms very tight to the arch of the foot in order to prevent arch collapse. Another cause of plantar fasciitis is a tight heel cord. The orthotic for this patient should include a heel lift to reduce tension on the Achilles tendon.
There are other biomechanical reasons why the fascia might be stretched. Each condition might require a somewhat different orthotic prescription in order to achieve the best clinical outcome. For best outcomes, it is critical to have a skilled and knowledgeable practitioner prescribe orthotics. Nothing determines orthotic outcome more than the skill of the practitioner.
