We are the suppliers of safety shoes in various industries Chemical and Fertilizer, Engineering and Manufacturing, Mining and Petroleum, Semiconductor and Electronic & Steel Industry and constructions etc. This shoes is looks good, but there is no specification about what is the weight of this shoe, having steel toe or not, what is size chart etc.We believe that most of the muscles are in our feet. Thus we should wear comfortable, light weight & best fitting shoes. The high weight of shoe will be problematic during work, so if you can get the detail of weight & size chart also for best fitting, then the other specification is exactly meet with constructions sites requirements.
