Have seen about one full season of use, approximately 40-50 days. I had to switch boots last year due to poor fitting, once the liner packed out it just wasn't happening they were a full size too big for me. But they still have plenty of life left in em if they fit your foot, heel lugs are a lil down but thats it. Looking for ballpark 140, gonna toss em on ebay if no one here wants em.
