I'm hard on shoes. It's not uncommon for me to go through half a dozen pairs of shoes, or more, each year. I maintain an active lifestyle, hiking, playing, camping, and working.
Water wears out a shoe quicker than anything else.
A few trips in and out of the creeks, puddles, and swamps, and they just come unglued. If I do not happen to dissolve my shoes in water, then I wear out the soles on gravel. It has always amazed me that tire companies can manufacture a tire and warranty the tread for some 50,000 miles, yet I can wear out the sole on any ordinary shoe in less than a year. Really, I have never been quite satisfied with conventional shoes, and it's not just because I wear them out so easily. Mostly it is because I do a lot of camping, and ordinary shoes have a lot of drawbacks for this type of lifestyle.
