Further research into ankle inversion injury studies provided us with these guiding stats:

  1. Ankle inversion time (from start of inversion to moment of injury) based on ground impact force varies from 40ms to serveral hundred ms. [1]
  2. The angular velocity threshold for ankle inversion injury is ~400 deg/s. [2]

BetterGuards (our competitor) has done extensive studies into this space - their research supports our basis that there is great merit to an ankle inversion prevension device that provides freedom of movement in other directions of ankle motion:

Athletes prone to reinjury after lateral ankle sprain may benefit from brace designs that allow for full sagittal range of motion but restrict only frontal plane motion. [3]

We just need to make our product to be better than BetterGuard’s (call it the BettererGuard).
