Strange at first but nice after a while
These definitely take some getting used to but feel great once you do. It almost seems like it massages your feet as you walk. These are basically little air pillows that move around back and forth as you walk. Think of it as those packaging air pillows that you get when you order something online, except these have less air in them and are for your feet. Very hard to explain but it was very weird to use them in the beginning. After about a week or so I started to get used to them and kind of like it. I use it in my every day shoes now. As far as how effective they are, I really have no idea. All I know is that I like them. Can I live without them? Sure but since I have them I'll continue to use them until they break, which might take a while.
