Teva Men's Waxed Canvas Durban Tall Boot, 2 Colors

How true are these to fit? if you have a wider foot it usually makes sense to buy a 1/2 size bigger in a med so I’m wondering what the width different between a 10 and 10.5 is

According to the size chart in the Specs tab, the difference is about 2/9"; no mention of the width.
