flip flop 3d model

"A minimalist, low-profile outer-sole attachment for a shoe. The 3D model features a thin, flat under-shoe platform shaped like an insole silhouette. The heel cup section is a separate, detached piece that can tilt upward, exactly as a mechanical split-sole mechanism. A small, compact actuator cylinder is subtly integrated under the midfoot hinge. No bulky leg braces, no heavy straps, no ankle collars. Only a clean, lightweight, streamlined bottom chassis that hugs the lower base of a sneaker. Engineering prototype for 3D printing."
