It does take a little bit of practice to learn how to walk in these and you will feel the burn in you calf muscles after a few hours, but they are great for improving your balance, especially if you make some of the tengu geta, I may try making some in a future instructable but all I have to go off of are pictures.
Step 1: Some Basic Terms & Types of Getak
Ha - the teeth on the Geta
Dai - the board on the Geta that the foot is on
Most Geta are made from paulownia a light weight wood, but mine are made oak just becasuse it was easier to obtain.
You can use the following instructable to make the geta http://www.instructables.com/id/Make-Your-Own-Geta-Sandles/
I will basically show you how to make the hanao for the geta which are far more comfortable and look more traditional then just the nylon cord I first used.
