I purchased these May 2012 - it's now Oct 2016. 4 years 5 months and it's time for another pair and I am buying these exact same boot. They have been great and offer extremely good value for the amount of abuse and use I put them through. They worked perfectly for me and as such I am BUYING another pair.
1st pair lasted me 4 years and 5 months after nearly daily wear and abuse - IN Short I am getting another pair now.
