OK - I'm going to purchase a set of these boots. My challenge is deciding which one. I would be going with the 3.5mm AeroHead for early and mid season, not the 7mm. Will likely grab a pair of mucks for the winter which I have used in the past. For those who have made the same decision, what made you choose one over the other? Looking to skip the marketing language because I personally can not see much differentiation from any of the popular boot companies making this style. I plan on heading to Cabelas to try them each on however, want to get some research in before that. Would appreciate any opinions in advance. I wanted to add that many of my hunts have me covering 2-5 miles so, comfort for long walks are very important.
