I love these footbeds. I am a mailman, so I am out walking all day long. I developed a good case of Plantar Fasciitis close to two years ago, and my doctor recommended I try these out. After a few weeks of wearing these inside my shoes for work it cleared up and I have had no issue with it since. These easily switch between shoes and boots that I have. I'm probably on two years with the same pair, and they are getting a little worn down (but very usable) and I just ordered my second pair. Only note is that on certain pairs of shoes or boots (usually my work-related ones) you may have to swap out the insoles with something a little flatter or less-thick since these will raise your foot up a little bit inside the shoe causing it to feel a little tight right in front of the ankle. Also, when you first use them it might feel a little wierd on the balls of your feet, but give it a few days and you'll get used to them and probably feel less foot pain.
