fwiw, Mizuno are notorious for overbuilding shoes, within the running community they make some of the most aggressive shoes in terms of heel height and various stability and motion control additions to their shoe designs. Their whole approach to running shoes is that everyone has problems with their feet and there is a shoe in their lineup that can fix it. I'd suggest you look for a more neutral trail shoe for starters that will allow your feet to get some sensory feedback from the trail yet still provide protection, as well as move more naturally with your body. Not saying you need to go all "barefoot" or minimalist, just something less aggressive than a pair of Mizuno Wave Nexus. General rule of thumb, if the shoe fits, feels good, works for your feet and intended conditions/activity, and doesn't give you troubles, then stick with that. Try some shoes out and see what works.
There are thousands of people running ungodly distances through the same trails and mountains people are walking up and down in. Do trail running shoes work for hiking? Absolutely. Are trailrunning shoes right for everyone? Nope. It's all about perspective and preference, in backpacking circles the idea of not using boots is still a new concept to some, which is silly really. Hiking is walking, it is a low impact, low intensity activity, it rarely requires any real 'technical' footwear, despite what the REI salesperson will tell you.
