Cowboy boots aren't harmful to your feet, back, or knees. In fact, they are as comfy as any other type of footwear. You'll be alright going around in cowboy boots unless the heels are too high, they don't fit correctly, or you have a specific health problem. If this is the case, then ask yourself if these problems can be fixed rather than avoiding wearing cowboy boots. The main thing that could harm your knees is long-term use of hard shoes. The pressure that is placed on the joints each time you step into such a shoe can lead to wear and tear, which over time may cause pain or stiffness. However, even regular exercise shoes can be hard on the knee if you use them every day. That's why it's important to find out what kind of foot gear you should be using and avoid using any that are not appropriate. Cowboy boots are not designed to be worn every day. If you need to walk a lot because of your job or life style, then you should choose shoes that provide more support. These might be work boots, hiking boots, or tennis shoes. It's best to avoid wearing high-heeled shoes if you are not used to it since it can lead to ankle injuries. Spending time on hard surfaces also increases your risk of developing arthritis. The most common place to experience this problem is the hands with rheumatoid arthritis being a second diagnosis to know.
