Spring Ankle

$250.00

  • 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 and Stray Dog Strength, 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.
