  • The ankle is where speed starts. Weak or poorly positioned ankles lead to energy leaks, slower ground contact, and increased injury risk.

  • The Spring Ankle trains athletes to develop stiff, reactive ankles—crucial for sprinting, jumping, and changing direction at game speed.

  • Designed by Cal Deitz, created by Chris Korfist

  • Inspired by principles from Triphasic Speed Training, this tool reinforces optimal mechanics like Spring Ankle Positions (see chart for details), teaching athletes to absorb and redirect force efficiently.

    • Reinforces Sprint Mechanics: Trains dorsiflexion and shin angle for efficient ground contact and quicker turnover.
    • Builds Elastic Strength: Enhances the lower limb’s ability to absorb and release force.
    • Boosts Speed, Agility & Power: A stronger ankle improves performance in all explosive movements.
    • Reduces Injury Risk: Improves joint integrity and reduces stress on the Achilles, knees, and shins.
    • Easy to Use: Integrates into warm-ups, speed drills, or return-to-play sessions on any surface.
