0 mm, 1 mm, and 2 mm represent insoles with protrusion heights of 0 mm, 1 mm, and 2 mm, respectively. The subscripts ‘a’ and ‘b’ denote significant differences from textured insoles with 0-mm and 1-mm protrusions, respectively. DPSI Dynamic postural stability index, APSI Anterior-posterior stability index, MLSI Mediolateral stability index, VSI Vertical stability index, η²_p: partial eta-squared. P values marked with bold indicate statistically significant differences. Effect size (partial eta-squared) was interpreted as small (η²_p ≥ 0.01), medium (η²_p ≥ 0.06), or large (η²_p ≥ 0.14)
