The Springbak® Challenge protocol

  1. 1. Baseline week: three sessions, same surface, same shoes, best of three attempts.
  2. 2. Change one variable — install your Springsoles under your existing insoles.
  3. 3. Re-test in weeks 2 and 3 under identical conditions.
  4. 4. Compare bests, not averages. A tenth is real; a hundredth is noise.
