All my Ariats have been paddock boots, and right now I have three pairs: a pair of Heritages which is still going strong; pair of younger Heritages whose stitches broke on the top of the boot and the spur rest fell off; a Cobalt whose finish could not withstand normal barn chores and stained and scratched despite routine cleaning and the insert basically dissolved after 6 months of continuous use.
Bear in mind that none of these boots have been used excessively for more than a year or so, and have been routinely cleaned and conditioned. I hear Ariat used to make better quality, and my older Heritages seem more durable than the other Ariats I have. Also, Ariat laces are pathetic.
Here is a discussion on another forum about Ariat boots: I'm done with ariat!!
