Jeffrey, I can tell you I wear a size 49 Sidi which relates to a size 14 US. I do wear 14's with Salomon shoes, but I wear a size 13 in Vans. Since many outdoor shops carry Salomon you could give them a try and perhaps find the right size there. As for the width, I have been told Salomon is a "narrow footbox" shoe and they are perfect for me. If you find that they fit you nicely as well then I doubt you would need to go with the wider options. Hope this helps a bit.
Holy cow! This is a fantastic headlamp. I got it for a 10 mile hike in and found it to be super comfortable and incredibly bright. Others in the group complained about not being able to see 5 feet in front of themselves while I was looking up canyon walls 100ft high. The diffuser works wonders. This is a must have for serious night hikes.
