Mens Boots
Boots are used by men all over the world for a wide variety of different reasons. Everything from work to hiking to fashion. The biggest difference between boots and shoes is that boots are a lot taller and usually cover your ankle, and sometimes even more of your leg.
Cowboy boots were made famous decades ago because of their strength and how well they protected the legs of people who wore them. Hiking boots have a huge benefit over regular shoes because regular shoes don't cover or protect your ankle, which can be very dangerous when you're hiking, walking up and down steep hills. Hiking boots on the other hand secure your ankle, so if you do fall you won't twist of break your ankle.
But boots don't have to serve a specific purpose other than fashion. Plenty of people wear cowboy boots simply because they look good, not because they are ranchers or farmers.
