Update: I have worn this boot now for over a full year and now my second (half) loop through the Yosemite Eastern Sierra high camps. I also wore them all Winter long last year due to the heavy snow fall here in New York City. I will admit that i did treat myself to a new pair of SuperFeet insoles. I am proud to report that the Veggie Trekker Mark IV boot remains solid and ready for a third loop!
