Study Notes
Indications of Calluses
- Calluses indicate areas of high pressure or friction on the foot
Purpose of Footwear
- The main purpose of wearing sandals, shoes, and boots is to provide protection and support for the feet
Function of the Sole
- The primary function of the sole in a shoe is to absorb shock and distribute pressure evenly
Upper Shoe Components
- The part of the upper shoe that provides posterior stability and supports the calcaneum is the heel counter
Advantages of Leather Shoes
- Leather shoes are considered better because they are breathable, durable, and provide a comfortable fit
Thomas Heel Shoe
- The purpose of a Thomas heel shoe is to provide support for flexible flat foot by limiting excessive pronation
Flexible Flat Foot vs. Rigid Flat Foot
- The main difference between flexible flat foot and rigid flat foot is the ability to form an arch when the foot is not bearing weight (flexible) or the inability to form an arch even when the foot is not bearing weight (rigid)
Characteristics of Pes Cavus
- The characteristic feature of Pes Cavus is a high arch, which can cause pressure points and calluses
Foot Orthotics for Rigid Flat Foot
- A molded polyurethane foam backed by microcellular rubber is used for rigid flat foot to provide support and cushioning
Custom Molded Foot Orthosis
- The function of a custom molded foot orthosis with elevation of anteromedial calcaneum (UCBL) is to provide support and correction for flexible flat foot by redistributing pressure and limiting excessive pronation
Test your knowledge about the functions of shoes and their importance in lower extremity orthotics and prosthetic alignment. Explore how well-designed shoes can minimize stress on the feet, provide support, and act as shock absorbers.
