II. Gait mechanics: Overpronator

  1. Physiology
    1. Feet roll inward
    2. Low arch
  2. Determination
    1. Wet bare feet leave a wide imprint on cardboard
    2. Old Running Shoes are most worn at medial sole
  3. Risks
    1. Joint and Muscle Strain
    2. Back pain
  4. Shoe type
    1. Motion Control Shoe (see below)

III. Gait Mechanics: Underpronator

  1. Physiology
    1. Minimal inward foot rotation
    2. High arch
  2. Determination
    1. Wet bare feet leave a narrow imprint on cardboard
    2. Old Running Shoes are most worn at lateral sole
  3. Risks
    1. Less shock absorption
  4. Shoe Type
    1. Cushioning Shoes (see below)

IV. Shoe types: Motion Control Shoes

  1. Indication
    1. Overpronator
  2. Determination
    1. Midsole (between outsole and insole)
      1. Lateral midsole is one color, and medial another
    2. Arch (medial) side of Outsole
      1. Different color/material with more medial support
    3. Arch (medial) side of midsole
      1. Plastic support provides additional medial form

V. Show Types: Cushioning shoes

  1. Indication
    1. Neutral or Underpronator
  2. Determination
    1. Lacks above motion control indicators
    2. Feels more cushioned

VI. Suppliers: Replace the shoe every 500-700 km (312-438 mi)
