This paper aims to describe the realization of a proposed orthosis, made from an airy and lightweight low-temperature thermoplastic, used in the case of foot drop for supporting, stabilizing, and correcting the ankle joint in the process of locomotion. The described solution might be seen as accessible work with low-cost materials and little technical knowledge. Besides this, it can be personalized to the anatomy of every user, due to the thermoplastic’s properties and it is composed of two parts easily connected through a quick-release band and Velcro. Thermoplastic can be modeled after being kept for a couple of minutes in water at a temperature of around 70 °C. The critical study indicates an abundance of available, on the market and not only, technical solutions that imply different materials, solutions, and methods including FES- Functional Electrical Stimulation. The paper also presents a bibliographic study made to understand the relevance of some keywords/terms, specific to this study, in a recognized database.
