I just got a new pair of irish setter elk tracker boots with 200 grams of thinsulate. Best boots I haver ever owned! Wearing them is like stepping on baby bunnies, sooo soft! After a short break in period I took em out on the muzzy, hiked my butt off and never had any sore feet issues. You get what you pay for when it comes to boots. I learned that a long time ago. 189.00 bucks is a lot but cheeper than foot problems!
