Looks like the Navy is looking to follow suit. This week's edition of Navy times says "Navy on verge of nixing barefoot sports shoes". However, this is the part of the article I found interesting: Well, no kidding. You shouldn't use any piece of equipment unless you're properly trained on it. You shouldn't use any equipment in the gym unless you're properly trained. Would you forbid Sailors from working out with weights because they "might" get injured from improper use ? The whole thing is ridiculous. Also, this caught my eye: There is no prohibition that I'm aware of against using these shoes with the PT uniform. I specifically contacted the Uniform program office and asked that question. The reply I got was "The Navy has no policy regarding the use of these shoes with the PTU".
