Expensive insoles. It has become nearly second nature to buy replacement insoles when we buy boots these days. With the exception of those who need custom orthotics to compensate for legitimate foot trouble you do not need new insoles. In fact, here's a little tip from some hardcore hikers: you don't even need insoles at all. None. If you're the kind of person who hikes a lot, like 75-200 miles per month, then you probably have the classic hikers foot (long and narrow) and you may have found yourself never finding just the right fit with your boots....always some heel slip, too tight, heel pressure, whatever. In my experience, a lot of these problems can be solved entirely with the total removal of all insoles. Take them out, stick them in the pack, put on some wool mountaineering socks, lace snugly, and hike. You'll have some free play in the boot but still snug and comfortable with no heel slip or toe bang.
Second, I see a few clowns out in the woods from time to time who have mistaken hiking for a day at Camp Rambo. I have no doubt that there are some places in the US where hiking is legitimately dangerous but, seriously, if your outdoor recreation involves mingling with drug cartels and human traffickers I'd just find a new form of recreation. Apart from these scenarios there are zero good reasons to pack handguns or giant military knives. If you're packing heat and running around like Rambo in the woods because you're afraid of running into a creep, I hate to tell you this, but, you are the creep you've been waiting for. If you think guns and knives are going to protect you from wildlife or maniacs you're out of your mind. You don't have the training or the background to do anything but get yourself wounded or killed or, worse, accidentally ruin somebody else's life. Besides, if you have walking sticks and bear spray you have all the resources to defend yourself from anything that poses a risk.
Third, don't waste your money on subscriptions to hiking or backpacking magazines. The whole world of print magazines is a total joke and has been for nearly two decades, whether they be devoted to body building, guitars, or whatever else. They are total wastes of paper and money, rehash the same old content over and over, and are so filled with ads that there's really no room left for anything substantial.
