I did not purchase through Amazon but these were issued to me through my employer.  When first putting them on, these were the most uncomfortable shoes I have ever worn.  They were incredibly rigid, provided zero arch support, and there was a lot of extra room in the toe area.  After 8 hours on my feet, I could barely walk.<br /><br />However, once they were broken in, they did gradually become more bearable.  That though, took about a month.  But, once that happened, the tread began peeling from the toe and sides, making it easy to trip.<br /><br />Overall I would not recommend these shoes, nor would my union as they also recalled them for the reasons I listed above.
