I had worried these shoes for an 8-week internship in a workshop. There I had a day at standing workstations, which for me represented in these shoes no problem 8 hours. I have shoe size 47 2/3 and was very satisfied with the purchased 48. Could test only 8 weeks, the shoes, but I found no signs of wear during this period. Even the lettering around I was scared after reading the other recessions held. Conclusion: For the occasion I described optimum very cheap option. How does that relate in continuous use under severe conditions, however, I am unable to say.
