The midsole is the “core buffer layer” 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. 하지만, 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, 마모 저항성과 형태 유지력, 압축 후에도 빠르게 원래대로 복원될 수 있으며, 오랜 시간 동안 안정적인 지지 성능을 유지함. 또한 우수한 내수성과 내식성을 가지며, 습기와 오염된 기름과 같은 열악한 작업 환경에 적합함. PU 중창의 단점은 EVA보다 비용이 높음, 적절히 관리하지 않으면 고온 다습한 환경에서 가수분해와 노화가 쉽게 발생함. Yinghao의 PU 중창 안전화는 가수분해 방지 기술을 적용하여, 중창의 수명을 연장하고 장기적으로 신뢰할 수 있는 성능을 보장함.
EVA와 PU 중창 외에도, 강판 중창과 라텍스 중창과 같은 특수 중창 유형도 있음. Steel plate midsoles are mainly used to enhance the anti-puncture performance of safety shoes, suitable for construction, 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.
