These are professional-grade safety shoes that I used at work. I used them for about a year, but in reality, I only wore them for about a month and then stored them for about two years. ・Basic Specifications: Features wide-area reflection and slip resistance! Uses retroreflective mesh. Easy to walk in with a non-slip outsole. ACM resin toe cap protects toes securely, even though it's lightweight. Uses a highly elastic EVA midsole with high cushioning. Designed to absorb impact on the heel. Feel free to ask any questions!
