I have hiking boots. But unless I'm going on a long hike or have a heavy pack, I find myself wearing not hiking boots, but trail runners. Is that OK? I mean, I know that it's best to give something with more protect and support to your feet while you're out hiking, but I don't always think I need my boots which can be too heavy. When I'm in my trail shoes I keep an eye for sharp rocks since the soles are thinner, but overall it's pretty much the same experience as hiking with boots.
What are you thoughts about this? I think @fallingwater might have a lot of them!
