Foot Mechanics and Orthotics, a free health course on Tomo

Foot Mechanics and Orthotics

Understand how the arches, joints, and tendons of your feet support every step. Learn to decode wear patterns, balance ground forces, and select the right orthotic support.

Like Duolingo, but for Foot Mechanics and Orthotics. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.

A short one: 10 levels across 2 sections, about 20 minutes end to end, roughly 4 days at five minutes a day. It moves through Reading Your Stride and Structure and Applying Orthotic Solutions. It starts from scratch.

What you'll learn

Key ideas in Foot Mechanics and Orthotics

  • A static wet footprint only shows the arch when standing still without gait forces
  • Dynamic movement adds bodyweight and impact that can flatten an arch that looks stable while stationary
  • Orthotics must match dynamic foot motion rather than just static resting shape
  • Heavy wear on the inner rim of the shoe sole reflects the foot collapsing inward (overpronation)
  • Wear isolated along the outer border shows a rigid foot failing to roll inward and absorb shock (underpronation)
  • Tread wear patterns reveal how the foot redirects ground force across the sole
  • The plantar fascia band contracts and tightens into a shortened position while resting overnight
  • Sudden weight-bearing on the first morning steps tears or violently re-stretches the tight fibers
  • Night splints and supportive orthotics work by keeping this band from shortening during sleep or collapsing under load
  • Viewing shoes from behind on a flat surface exposes whether the heel counter tilts inward or outward
  • Inward tilting reveals rearfoot collapse, signaling that inward rotational strain is already traveling up toward the knees and hips
  • A shoe tilt test spots structural breakdown in shoe cushioning and foot posture before joint symptoms appear
  • The foot rests on a tripod of heel, base of big toe, and base of little toe
  • The inner medial arch is high and flexible while the outer lateral arch is lower and bears weight
  • The transverse arch runs across the middle of the foot like a dome to distribute body weight
  • Pronation unlocks the foot joints so the foot becomes soft and absorbs ground impact
