I don't think your pain is due to wearing trail runners, but rather it's because you're wearing the wrong trail runners.
+1 on the thought that you may have a pronation problem (collapsing inward).
Remember, trail runners are running shoes. (We just use them to hike in.) Like road running shoes, trail running shoes are designed and built for correcting/taking into account a variety of certain biomechanical issues, such as arch type, pronation, suponation, stability, cushioning, light weight, low milage, high milage, etc. In short, you need the correct shoe that matches your biomechanic and running style needs, ie forefoot striker or heel-toe foot strike.
For example, if in fact you pronate a little, a stability shoe may work, but if you pronate excessively, you may need a pronation motion control shoe. Then you would also need to know your natural foot strike pattern to choose a shoe with the correct last shape and midsole support for you. For example, a person who pronates and is a forefoot striker will need a different shoe than one who pronates but strikes heal-to-toe.
In short, there's more to it than just emulating what shoes other hikers are wearing or just buying the lightest model. You could pay $150.00 but if you're in the wrong shoe, you'll get injured.
The best place to start is to go to a running specialty store and work with a knowledgable sales person who can examine your foot, watch your gait and foot strike, etc. It is also still a good idea to bring your current runnng shoes with you so the salesperson can look at the wear pattern. You can also check online resources like roadrunnersports.com or runner's world for more information.
