• I don't know what an Italian 11 is, but I typically wear a 10.5-11 American (depending on the brand), and an 11.5 of this boot fits with room for a pair of thick wool socks.

  • I have two pair of Alico hiking boots, including the Ultra. Both pair are marked in American sizes.

  • Although these boots are American sized, they have very thin insoles. If you replace them with thicker insoles you may want to go up by one-half size, and then adjust the size with the thickness of your socks. I apologize for not including this information in my original answer.

  • All sizing on our website is in US sizes unless otherwise indicated on the specific product page.
