Mean differences and statistical significance for kinetic variables for shod and barefoot walking.

Variable	Shoe Condition	Authors	n	Weighting	Mean difference [95%CI]	Statistical significance: z Score(P)	Heterogeneity: I2%
Vertical ground reaction force (%BW)	Walking	Kristen et al. [15]	30	100.0%	6.30 [-2.82, 15.42]	1.35 (P = 0.18)	N/A
Anterior Posterior Max GRF (%BW)	Walking	Kristen et al. [15]	30	100.0%	-0.90 [-3.66, 1.86]	0.64 (P = 0.52)	N/A
Anterior Posterior Min GRF (%BW)	Walking	Kristen et al. [15]	30	100.0%	-1.00 [-5.99, 3.99]	0.39 (P = 0.69)	N/A

A negative mean difference value indicates a decrease during shod walking compared to barefoot walking. N/A indicates not applicable
