Bought a pair of Caterpillar walking boots in about 2007 and gave them some serious hammer, climbed mountians etc.. decided they were getting a bit tatty this year so bought another pair. 6 months later, soles worn through no receipt, managed to talk the manager into giving me store credit. Only boots they had that I liked were identical to the last pair, ho hum at least I will get another 6 months out of them.
The original decent ones had an oil resistant sole these don't, lesson learned.
