Abstract

A dynamically adaptable sole support frame includes a central skeleton layer. This central skeleton layer comprises a forefoot section, an arch section, and a heel section, arranged sequentially from front to back. The forefoot section is longitudinally cut to form several slits and a push plate, while the arch section has several positioning protrusions extending at intervals on both sides. Through the slits and push plates in the forefoot section, foot deformation is concentrated in the forefoot during both active and inactive states. With different left-right, forward-backward, and lateral movements, the forefoot adopts different bending postures, creating a dynamic plane in different directions of movement and allowing the foot to return to a natural posture during movement. The positioning protrusions in the arch section and the support plate in the heel section form an arc-shaped cushioning mechanism in the heel. When the heel strikes the ground, the multiple positioning protrusions create multiple cushioning points, naturally dispersing pressure and providing strong support to cushion and stabilize the foot.
