From: A comparison of gait biomechanics of flip-flops, sandals, barefoot and shoes
Ensemble curves of ankle sagittal plane angle (A) and moment (B) and frontal plane angle (C) and moment (D) of all four footwear conditions, where the solid line is for barefoot, dash line for sandals, dotted line for flip-flops, and dash-dotted line for shoes.
