these shipped so fast! :D they only took 5 days and i was so surprised when they arrived in the post! okay, here is a review from someone who has been wearing these same insoles for over a year. you are not going to be able to wear them at full height right away, you're going to need to adjust to them over a few months. it takes time to get used to each height and learn how to stay balanced, but you tend to know when you're ready to move up. you need shoes slightly bigger than your normal size to fit them, and you are going to be clumsier on your feet unless you've grown used to them. also you need to take them out of your shoes every so-often to get rid of dirt. however, these are super comfortable and can be cut down to any shape you need. they're perfect for everyday use and have been a huge confidence boost since i bought them :D
