Dude, I never thought I would be a fan of a calf height boot but I just decided to give it a go on a whim. These boots are seriously fantastic. I went up a size, and can wiggle my toes with space for a thick merino sock in the winter. The fit is perfect. I almost exclusively hunt the palo duro canyon hunting aoudad and mule deer in some of the most rugged terrain in Texas. Tons of up/down/side hilling on cliff sides and rock slides where a slip could cost you your life. These boots fit the dang bill. Without a doubt the most rugged pair of boots I've ever owned and they are stupid comfortable. I will wear these boots until they die everywhere for every hunting application. Just do it. They're worth every penny.
