I read many reviews before buying these amazing boots, first and foremost this is a boot and you really need to wear thick boot socks to get the most comfort out of these.  i actually bought 2 sizes up because it was 75% cheaper than my size, and i wear them comfortably for 12+ hours (while on my feet) my girlfriend hates them because sometimes i wear them in bed, i'm kind of a savage like that..  the metatarsal does not seem to bother the top of my foot despite it not being a flex guard ?  i bend,kneel,walk and squat for most of my day.  I had planned on buying the timberland pro endurance insoles for these however they come with a very nice memory foam insert that i'm okay with.
