Purchased a pair of these a few months back, I'm starting to get my legs ready for a Sept hunt and I've been wearing these boots hiking every chance I get. The last few trips I started getting a hot spot on the back of my left heel after about 4 miles. I've got a set of insoles coming to replace the factory insoles. I'm hoping this will help with the slip. I've laced them every which way and nothing seems to help. Any one have a suggestion? I like the feel of the boot but this is a serious problem for a backpack hunt. just wear them until the callous builds up? I wear boots all day so my feet are used to the wear and tear.
