The 21st century must be here; you can now get carbon fiber in your shoes. Not that anyone will notice, but perhaps later on they’ll start putting them on the outside like carbon fiber car hoods or something.
While not all of these new boots use carbon fiber, composite-toe safety shoes are becoming commonplace, using fiberglass or similar materials. Lighter than and just as strong as steel toes, they help to keep your dogs from barkin’ too loudly at the end of the day, without sacrificing any peace of mind. Most of the larger manufacturers such as Wolverine, Bates, and Hytest, have one or more offerings with composite toes, and they generally retail for a few dollars more than their steel-capped counterparts.
Whether a lighter shoe is worth the extra cash depends on how much value you place on comfort, but given how high the cost of good safety shoes can be, an extra $10 or $20 seems like a good trade.
