Burns & Joubert 2024, Running shoes of the postmodern footwear era (narrative overview)

Narrative overview of advanced footwear technology (IJSPP 19(10):975-986, DOI 10.1123/ijspp.2023-0446). Among the findings reviewed, a bench test found small energy-return loss in a worn PEBA shoe (84.5% to 82.9% after ~500 km), contesting on-foot economy-decay findings. The worn-shoe data are one component of the broader review, not its primary scope. Moderate/contested.
