So being new to hunting in Montana I recently bought some Danner Pronghorn Classics for bear and early elk season. therefore they are not insulated. My question is this... I bought a size 9 but an 8.5 fit my foot also, however it was a little tighter on my foot. With the size 9 I have a little bit of wiggle room...meaing less than 1/2 in front my heel to the heel of the boot if I slide my foot all the way forward. If I wear a thin sock to wick away moisture and then my underarmour cold gear sock, i dont move as much. Do I go take the 9 back and get the 8.5 or keep the 9? The 8.5 fit with the same socks on, it just seemed tighter all the way around my foot, which seemed uncomfortable to a point? Guidance is needed for my unexperienced self, I have never needed boots like this before.
