Question 1

How should the snow hiking boots fit?

Accepted Answer

Tight-fitting boots should be avoided because they hinder blood flow, resulting in chilled feet
There should be some room for your toes, you want as little lateral movement in the boot as possible without feeling like your foot is being squeezed, and your heel should not lift when walking with the boot tied up
If you're in between sizes, fill up the extra space by wearing thicker socks or changing the insoles with bigger volume insoles

Question 2

Why can't I wear my ordinary hiking boots instead of snow hiking boots?

Accepted Answer

Waterproofing and insulation are the most important considerations
Most insulated snow hiking boots are waterproof right out of the box
The rubber or waterproof synthetic bottom allows you to trudge over puddles and thick snow without worrying about the cloth absorbing water
