They appear to be well made and would probably hold up, but the steel insert is too narrow and pinches the sides of my feet near the first knuckles of my big and little toes where the foot is widest. I would probably need two sizes larger to fit, but then the shoe would be too long. And I could buy the wider version, but the heel and mid sections would then be too wide and would probably make the shoe feel too loose for the work site.
