SHORT DESCRIPTION

The foot arch, a natural shock absorber for the human body, disperses impact forces during walking or exercise to protect the foot and lower limb joints. However, kids with fallen arches fail to provide sufficient arch support, making it difficult to effectively absorb shock during physical activities. This can lead to increased fatigue and discomfort and, over time, may cause abnormal development of the lower limb bones or postural imbalance. ANTA ARCH PRO offers kids with fallen arches an effective foot support solution across all scenarios from daily walking to frequent exercise. ANTA has collaborated with Sinopec and BASF to develop ‘polyurethane microporous elastomer’ as the core material for arch support, which is applied to the lower layer of the midfoot area to achieve dynamic arch bridge technology. This marks the first use of auxetic materials in the footwear and apparel industry. The material, with a unique grid structure, makes adaptive adjustments based on impact frequency: under low-frequency impacts (like walking), it delivers a soft feel and excellent shock absorption for relaxed comfort; during high-frequency impacts (like running), it provides firm, resilient support to prevent arch collapse or overpronation, enhancing dynamic support performance by 37%. The optimized arch bridge-like 3D structure precisely fits the foot arch, while its fractal ratio (the ratio of the medial side to the lateral side) and height are respectively increased by 26% and 20% for balanced support and reduced fatigue. The upgraded outsole balances support, propulsion, and smoothness: precisely tuned thickness in the forefoot and heel facilitates rapid response; the increased heel curvature ensures a smooth weight shift; medial arch fitting technology delivers natural support for superior comfort. Toe-flex technology, inspired by the bare foot, equips the forefoot area with transverse curves and longitudinal grooves to improve flexibility by 22% for natural, efficient force application.
