After using steel toe boots that weighed 5 lbs each (or more) and felt like 100 lbs each by the end of the day, these shoes with the plastic toe protection were a welcome relief.
I don't know if I'd wear plastic tipped shoes if I was a production worker out there 8 hours a day, but for my use (frequent, but not continuous, forays to the production area), they serve their purpose. And, they are manufactured and tested to the ASTM specs.
I'd rather have a shoe that wasn't as gaudy though...something simple and plain would be nice. This is why I gave them 4 stars rather then 5.
