The world’s first 3D‑printed sports recovery shoe officially authorized by FIFA made its debut at Hall C of the Jinjiang International Footwear Expo.

The product was jointly launched by Shanghai Accumulation Technology Co., Ltd. and Xin Kaijia Machinery, using lattice technology to reconstruct plantar biomechanics, providing a new “mechanical intervention” solution for foot fatigue management after high‑intensity exercise.

The development took 18 months, during which Accumulation Technology deeply collaborated with the Medical 3D Printing Innovation Research Center of Shanghai Jiao Tong University, undergoing biomechanical testing and trial adjustments by top athletes. Fan Yilin, world champion on the uneven bars at the 2017 World Gymnastics Championships, served as the chief experience officer. She said that this shoe allows the feet to quickly relax from a tense state, which is crucial for extending athletic career lifespan.

The core technology overturns the mechanical limitations of traditional foamed materials (such as EVA). The five major performance breakthroughs include:

Negative Poisson’s ratio effect – actively absorbs impact. The unique NPR structure causes the material to gather inward when compressed, acting like a high‑performance air suspension to absorb shock waves, efficiently converting landing energy into rebound power.

Topology‑optimized zoned support – spreads plantar pressure evenly through a face‑centered cubic lattice algorithm. High‑density lattice in the heel provides strong locking, while low‑density lattice in the forefoot offers soft landing, avoiding fatigue damage risks.

High energy‑return cycle – energy return rate exceeds 75%, far above the 48–50% of traditional TPU materials, making walking easier and supporting low‑load post‑game recovery.

Active airflow system – 65% precision grid porosity creates air convection channels in the sole, increasing heat dissipation efficiency by 40% compared to traditional materials, quickly cooling and dehumidifying feet after intense exercise.

Intelligent parametric design – based on big data of plantar pressure distribution, it achieves seamless hardness transitions across different zones, finding the optimal balance between “too soft (insufficient support)” and “too hard (excessive pressure).”

The product line covers three levels:

Post‑game recovery flagship model – TOAST slides: Designed for the “50 meters off the pitch,” using the negative Poisson’s ratio lattice structure for maximum energy absorption, providing a fast path for top athletes from tension to relaxation.

Sport‑casual model – CALM sneakers: Hides competition‑grade lattice cushioning under a classic silhouette, giving daily city walks and commuting a “recovery property” and achieving seamless wearable technology.

Minimalist travel model – SLICE slides: Extremely lightweight and compressible structure delivers a barefoot‑like feel, turning precise mechanical support into a portable comfort zone, ideal for frequent business trips and daily relaxation.
