I wore it for a year. Although the inside of the shoe did not deteriorate so much, outside the toe part, especially cracks became conspicuous, so I replaced it with other safety shoes. Machining is done, metal cutting chips came into the shoes, it was a little troublesome. Also, it gets somewhat steamed in the summer. I do not know for that reason, but in the winter the fingers become simmered. Perhaps the heat gets caught in the shoes, I think that the fingers of the foot are cooled by the cold heat. I also realized it in winter, but the upper fabric is fluffy. I do not mind at first, especially in winter. Although Safec shoes of Siebeck are light and cheap, it is good, but I have never met shoes "I was satisfied overall."
