Attached is a picture of my first pair. They were the insulated version and get pretty hot when worn in the summer. I have had these 3.5 years and they are still comfy. Only replacing because the sole has worn out. Ive Worn them every day. I am 350lbs and have never had a pair of boots last this long and stay comfortable. I love these things. Have been comfy since day 1, no break in period. Buy them. You won't regret it!
