"Every boot fits someones feet perfectly, unfortunately it may not be your feet." I'll say amen to that quote. I have been wearing some sort of boot for 50 odd years, and I've probably tried most styles and many makes. I've spent hours walking around the store in a pair of boots trying to determine whether they fit right or not. Most of the time I have settled for something that turned out to be unsatisfactory over time. I'm a surveyor, so I wear boots of some sort 95% of the time, either working or hunting.
I've discovered that if you continually wear boots that don't fit right, eventually your feet will pay for it.
I always subscribed to the notion that a person needed a stiff, heavy-duty boot for the rough, steep, rocky terrain we encounter here in Idaho hunting for elk. However,after having some major problems with my feet due to boots that did not fit right, I finally broke down and ordered a pair of Russells because they custom make them for your feet. I had to send the first pair back because I evidently did not measure correctly. Once I got the right measurements, the result has been very satisfactory. They are moccasin in construction with a very thin sole and are termed "minimal", meaning no arch support and no heel. I have plenty of ankle support, partly because I have strengthened my feet and ankles by running in "minimalist" footwear and wearing them while hiking around in rough, steep country. Balance is better and traction is much better than hard, stiff lug soles.
Just remember, you can keep physically fit in all respects, excercise, climb mountains etc. but if your feet give out you are done for. It's tough to elk hunt without being able to hike.
