Infographic titled "Foot & Ankle Complex" with simple line illustrations, a pie chart and radar chart, and bullet points defining the foot (26 bones, 33 joints, 100+ muscles/tendons/ligaments; acts as a lever and spring), explaining function and mechanics (force transfer, spring storage/release, ground-contact transition <100 ms), and describing control and stability (intrinsic "foot core," preventing energy leaks, proprioception) plus a small running and stair-training graphic.
