Course Outline:

Callus patterns and what they mean

This course explores the etiology, common causes and the most common patterns of foot calluses. Gait cycle biomechanics are reviewed. There is an emphasis on the pathomechanics leading to callus formation as well as footwear factors. It is assumed the course participant has a basic knowledge of foot anatomy and biomechanics.

Learning Objectives

  • Present the etiology of blister and callus formation

  • Review the gait cycle and the biomechanical events relevant to callus formation

  • To review pronation and supination motions of the foot and how they relate to low and high gear push off

  • To review the 3 rockers and how they can relate to callus formation

  • Discuss the more common callus patterns in feet

  • Describe the foot pathomechanics that lead to callus formation


Why Take This Course

Understanding callus formation is fundamental for anyone involved in foot care, biomechanics, or lower extremity rehabilitation. This course provides a deeper look into how specific patterns of callus development reflect underlying mechanical and gait abnormalities. By exploring the etiology and biomechanics behind callus and blister formation, participants gain valuable insight into the body’s compensatory strategies and how footwear and gait dynamics contribute to tissue stress.


Through a detailed review of the gait cycle, pronation and supination patterns, and the three rockers of the foot, learners will develop a comprehensive framework for interpreting common callus presentations. This knowledge allows clinicians to move beyond symptom management and toward addressing the root causes of foot discomfort and dysfunction.


By the end of this course, participants will be able to connect visible callus patterns to biomechanical dysfunctions, make more informed footwear recommendations, and enhance their clinical assessments for improved patient outcomes.
