What material is a denver bar made of?

A Denver bar is primarily made of firm rubber. This choice is correct because firm rubber provides the necessary durability, flexibility, and shock absorption needed in orthotic devices and supports. The material must be sturdy enough to withstand daily wear and provide adequate support, especially in the context of correcting or managing foot and gait issues.

Polypropylene and polyethylene are both types of plastic that have specific applications in orthotics but do not offer the same characteristics required for the construction of a Denver bar. Chrome tanned leather, while used in some footwear applications, lacks the properties that aid in the type of support and functionality provided by firm rubber in this context. Therefore, firm rubber is the most suitable material choice for a Denver bar, effectively fulfilling its intended purpose in pedorthics.
