Abstract
Purpose: This study investigated lower limb variability when trained runners wore a minimal shoe for the first time. It was hypothesised that initial lower limb variability would be decreased in the minimal shoe condition due to lack of familiarity. It was also hypothesised that variability would increase over time as runners become more familiar with the condition. Methods: Testing included three 10 minute treadmill running trials conducted in runner's own running shoes, a pair of minimal shoes followed by runner's own shoes again. The shoe order was selected so as to establish a baseline value of variability in a runner's most familiar shoes followed by a perturbation which was the inclusion of minimal shoes. Continuous Relative Phase (CRP) relationships and kinematic values at heel strike were determined which allowed lower limb variability to be quantified. Results: Kinematic variability values were not statistically different between runner's own shoes and minimal shoes. CRP relationships did not differ between minimal shoes and runner's own shoes or over time. Conclusions: Trained runners did not change lower limb variability while wearing minimal shoes for the first time. Lack of familiarity does not appear to affect lower limb variability. The footwear included in this research study had similar cushioning properties to traditional footwear but with a different construction which may relate to similar values found between conditions. Investigating how runners of different abilities transition to minimal footwear should be focused upon to reduce risk of injury.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
