I am a heavy equipment operator by trade and it is mandatory safety toe for all. I only buy low composite toe shoes. Never could like cold steel in my shoes.
Never heard of Nautilus brand but looking at the limited choice composite toe shoes on Amazon, I saw these, and was sold on their looks.
 As soon as I tried them on I, knew there was a problem. When placed on my kitchen table the left heel was defective in that the outside of heel was about an 1/4 inch or so off the surface of the table. The shoe would rock and pitch as I walked.

 So much for the Nautilus Brand -(Made in China)- this good looking shoe is going back !. Hard and cheap outer sole also, sounded like tap shoes !.

Keen Utility Work Shoes introduced a new low composite... "Lexington and Albany". At least some Keen shoes are "Made IN USA" Cost a little more but Keen is high quality and one of the best.<a data-hook="product-link-linked" class="a-link-normal" href="/Keen-Utility-Men-s-Lexington-Composite-Work-Shoe/dp/B00A8DY94W/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Keen Utility Men's Lexington Composite Work Shoe</a>
