Aerostitch products and services have a legendary and well-deserved reputation among serious motorcycle adventurers. However, I have to report that I have had serious problems with their Combat Touring Boots (made by Sidi of Italy). First, after a year or so of use, one of the plastic ankle straps broke. Andy told me he had not encountered this problem before and send me a handful of replacements, showing why their service is legendary. However, after another six months of service, the velcro closures have failed completely, rendering the boots unusable. Aerostitch told me they have had a few other reports of this problem and promptly sent me a new pair. However, Mexican customs demanded a $140 duty, both when they were initially sent as warranty replacement and later resent as a "gift." Clearly, a failure of this sort is a serious problem for anyone travelling abroad. I believe my problems stem from the fact that I have walked quite a bit in the boots, thus flexing them a lot. Because the leather shell of the boots is very stiff, this flexing puts a lot of strain on the closures, both the plastic strap and the velcro. If and when I find a way to get my replacement boots, I will plan to always carry walking shoes. I suspect I will then have no more problems.
