I had a pair of Striker 2 boots that I bought about 4 or 5 years ago and they lasted about that long, and I still use them to go to the range and other things. They have held up great to this day, they just don't hold a shine anymore so I decided to get a new pair of duty boots. There was a slight problem with the zipper on one of the boots, it would unzip but if I tied the laces around the top of the boot there was no problem - I just had to tie them instead of using the zippers. This zipper issue started after about two or three years of patrol use in Alaska. No complaints there.<br /><br />I was so pleased with Striker 2's that I bought another pair. I noticed that the zippers on the model had changed. This zipper broke after one or two days.  There has obviously been some cost cutting going on and it is very apparent when you compare the pair of boots I had first to the new ones. When I buy Danner boots I expect to pay a couple hundred dollars and get five years of them.<br /><br />I would not buy another pair of these boots. I will be going with the non-zippers. I don't know if the durability of zipper boots is just not a feasible thing or if these are just cheap, but I would not recommend them.
