Plantar heel pain affects 4 to 9% of the population and is a common reason for consultation. Plantar fasciitis is the most frequent cause. Its diagnosis is essentially clinical, possibly supported initially by combination of X-ray/ultrasound. Ultrasound is the modality of choice to confirm the diagnosis. The prognosis is favorable, but the evolution can be long. Its management should be structured in a progressive manner, based on therapeutic education and physical measures. These simple measures have the highest level of evidence of effectiveness and should be implemented before proposing, sometimes too early, second-line therapies.
