This is a Study to Evaluate a Pre-confectioned Plantar Insole for the Treatment of Plantar Heel Pain

The pain visual analog scale (VAS) is a validated, self-assessment scale in which patients rate their pain by making a handwritten mark on a 10-cm line that represents a continuum between "no pain" and "worst pain." The pain VAS will be administered at baseline by the patient himself and at follow-ups.

A negative change from baseline will indicate an improvement in VAS score and, therefore, in local pain.

Foot function Index measures the impact of foot pathology on function in terms of pain, disability and activity restriction. The FFI is a self-administered index consisting of 23 items divided into 3 sub-scales. The patient will answer each question on a scale from 0 (best) to 10 (worst result), that best describes their foot over the past week. The pain subcategory consists of 9 items and measures foot pain in different situations. The disability subcategory consists of 9 items and measures difficulty performing functional activities because of foot problems. The activity limitation subcategory consists of 5 items and measures limitations in activities because of foot problems. Both total and subcategory scores are calculated.

The Foot Health Status Questionnaire (FHSQ) is a self-assessment and trustworthy instrument about health quality regarding specific foot health, initially developed to assess the results of surgical treatment of common foot diseases. It is made of questions regarding foot health and its impact on quality of life. There are 4 subscales: foot pain (4 questions), foot function (4 questions), footwear (3 questions), and general foot health (2 questions). For the subscales of pain, function, and general foot health, there is a 5-point Likert scale of no problems, pain, or limitations to severe problems, pain, or limitations. Responses to footwear questions are on a 5-point bipolar Likert scale from strongly disagree to strongly agree for statements regarding shoe fit, discomfort wearing shoes, and shoe wear available.

self-assessment scale in which patients rate their satisfaction by making a handwritten mark from the lowest satisfaction (0 point) to the highest satisfaction (10 points)
