There are a few flavors of the Elk Tracker with different insulation that have other subtle differences as well.
I have them (uninsulated) and can't remember the last time I wore them. As stated above, they're big and bulky and heavy. The sole also does a terrible job of shedding mud and each boot will easily carry an extra couple pounds of crap on the sole if it's mucky/muddy out which makes any hiking miserable. They are fairly comfy generally speaking. The uninsulated version has a lace lock that falls right on the ankle bone and can cause some uncomfortable rubbing, though I've never gotten a blister or anything.
If your feet sweat enough to get your socks wet, you're going to have cold feet no matter what. The biggest thing I have done to improve my comfort is to dress for the hike, not the sit. If you dress like you're going to sit still in 15° weather then hike a mile to get to a spot, you're going to be miserable. I dress in such a way that I start to catch a chill standing still, then layer up appropriately when I get to a glassing spot.
Whether insulated or not, the boots you have can probably work if the rest of your clothing is dialed in for your situation. Second season Colorado can be below freezing with lots of snow, or t shirt weather, or both on the same hunt depending on your location and elevation.
