I like to hike on my free time.  Have you ever been hiking? 
nope. but in new zealand a hike also referred to as a long vigorous walk is also called tramping!
That's a new term I've never heard before. What kind of shoes would someone wear hiking in your opinion? 
walking shoes if you're mostly walking, running shoes if youre mostly running. you would want the shoe to match the activity you do the most. also hiking is a popular activity worldwide and studies suggest that all gorms of walking, even long hikes have health benefits.
