英豪安全鞋
中底是安全鞋的 “核心缓冲层” of safety shoes, located between the outsole and insole. It not only bears the pressure of the human body and absorbs impact during walking and working, but also affects the wearing comfort, support performance and service life of safety shoes. As a professional labor protection brand, Yinghao has always attached great importance to the selection and optimization of midsole materials, providing diverse midsole options for different workplace needs. This article will elaborate on the common types of safety shoe midsoles, their differences, advantages and disadvantages, helping you choose the most suitable safety shoes.
The most common type of midsole in safety shoes is the EVA midsole. Made of ethylene-vinyl acetate copolymer, it is lightweight, soft and has excellent shock absorption performance, which can effectively reduce the impact on feet during long-term standing and walking, and relieve foot fatigue. Its advantages also include low cost and good flexibility, making it widely used in light to medium-intensity work scenarios such as warehousing, logistics and assembly. 然而, the EVA midsole has obvious shortcomings: poor wear resistance and easy deformation after long-term use, which will reduce the support performance of the shoes. Yinghao optimizes the EVA midsole by adding reinforced fibers, improving its wear resistance and shape retention while maintaining its lightweight and shock absorption advantages.
PU midsole is a high-performance midsole material widely used in medium to high-end safety shoes. Compared with EVA midsole, it has better elasticity, wear resistance and shape retention, 并且在受压后能够迅速回弹, 长期保持稳定的支撑性能. 它还具有良好的防水性和耐腐蚀性, 适用于潮湿和油污等恶劣工作环境. PU中底的缺点是成本高于EVA, 如果未得到妥善维护，在高温高湿环境下容易水解和老化. 英豪的PU中底安全鞋采用防水解技术, 延长中底使用寿命，确保长期可靠性能.
除了EVA和PU中底外, 还有钢板中底和乳胶中底等专业中底类型. 钢板中底主要用于增强安全鞋的防穿刺性能, 适用于建筑行业, mining and other scenarios with sharp objects, but they are heavy and affect comfort. Latex midsoles have excellent softness and fit, but poor wear resistance and short service life. Yinghao recommends choosing midsole types according to work intensity and environment: EVA midsole for light-duty and comfort needs, PU midsole for medium to heavy-duty and harsh environments, and steel plate midsole for scenarios requiring anti-puncture protection. All Yinghao safety shoe midsoles strictly comply with international standards, balancing comfort, protection and durability to guard every step of frontline workers.
