I go threw a pair of boots around every 4 months. It doesn't matter if they are keen, merrell, uggs, etc. If I go cheap cheap though they will only last a couple of weeks though so I still buy quality shoes but I don't like paying $120 a pair. I just find whatever is on sale at that time and buy a couple pairs of them. I bought 3 pairs of keens for like $55 each which I consider a steal on my last order. These will last me around a year and as one get wore out pretty bad they end up getting moved down to my hog pen boots and then I have my normal work and farm boots and then my nice boots even though they are all the same pair of boots.
