Peak positive tibial acceleration (g) for each condition (N = 28).

Condition	Mean (SD)	% change	Effect size (d)	P-value
Boot only (control)	2.22 (0.82)†	n/a	n/a	n/a
Flat insole	2.25 (0.89)†	+1.4	0.04	0.882
Foot orthosis	2.07 (0.75)†	−6.8	−0.19	0.018*#

Note: % change is relative to the boot only-control condition. ^†Data transformed prior to determining significance. *Mean difference significant at the 0.05 level compared to the boot only condition. ^#Mean difference significant at the 0.05 level compared to the flat insole condition.
