As with any footwear, having the proper measurements can make a big difference in geta fitting well or not. The positioning and height of the teeth, length and width of the sole, and placement of the thong are important to getting a good fit. Luckily for you and I someone has made a great calculator that'll give you all the exact measurements you need for your foot. Remember to follow the directions for measuring your foot since well-fitted geta will actually be a couple centimeters shorter than the length of your foot. You can find the geta calculator here
. Once you have measurements you can get your materials.
