As a fellow Northwoods hiker, I can tell you there is no such thing as overkill. This shoe is the only shoe that I would consider to be more aggressive than my Tubb's Couloir (replaced this year by simply the mountaineer). Aggressive traction means a word of difference if you plan on leaving the trails behind. I like going out into the woods, finding the steepest hill around, then marching straight up it. If climbing over fallen trees and down rocky escarpments sounds like fun to you, then get this shoe! If this sounds like perhaps it's more work than fun, and you would rather stick to the trails that those damned (*wink* I'm kidding!) CC skiers keep all packed down, then perhaps you could go with something a little lighter on bite.
I hope this helps!
Edit : Heel raisers are a nice option, but I haven't found a hill tall enough to warrant their use in Wisco yet. Maybe if you make it to the porkies in upper Michigan it might come in handy. But then again, I think overkill can be fun :D
