YingHao Scarpe di Sicurezza
La intersuola è lo “strato di ammortizzazione principale” delle scarpe di sicurezza, situata tra la suola esterna e la soletta interna. 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. Come marchio professionale di protezione del lavoro, 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. Tuttavia, 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, and can quickly rebound after being compressed, maintaining stable support performance for a long time. Ha anche una buona resistenza all'acqua e alla corrosione, adatta a ambienti di lavoro difficili come umidità e inquinamento da olio. Gli svantaggi della suola intermedia in PU sono più costosi rispetto all'EVA, ed è soggetta all'idrolisi e all'invecchiamento in ambienti ad alta temperatura e alta umidità se non mantenuta adeguatamente. Le scarpe di sicurezza in PU di Yinghao adottano la tecnologia anti-idrolisi, prolungando la durata della suola intermedia e garantendo prestazioni affidabili a lungo termine.
Oltre alle suole intermedie in EVA e PU, esistono anche tipi specializzati di suole intermedie come le suole intermedie in acciaio e le suole intermedie in lattice. Le suole intermedie in acciaio sono usate principalmente per migliorare le prestazioni anti-foratura delle scarpe di sicurezza, adatte alla costruzione, alle estrazioni minerarie e in altri scenari con oggetti appuntissi, ma sono pesanti e influenzano il 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.
