Geta are a form of traditional Japanese footwear or sandal with an elevated wooden base held onto the foot with a fabric thong to keep the foot well above the ground.
This version of Wooden Sandals has a rubber feet, so it doesn't make a lot of noise, I added some laser engraved Katsushika Hokusai print onto the Sandals so I can tell which one is right or left.
This project came about when I was at the Haystack Mountain school of craft. I realized that I left my sandal at home but luckily, I was living in the FabLab and have the access to a shopbot and some casting materials. I decided to make my own sandal out of my need.

Step 1: Measurement / Sizing
I traced my feet onto a piece of paper and figured out where to drill the wholes for the straps (the hole right next to the big thumb) After taking the measurement, I model the sandal in SolidWorks. It starts out as a 3D design, but is was taking way to long, so I did the cut out in 2D for faster cut time. For this, you can use Illustrator or any other vector drawing software.
Step 2: Cut Outs / Milling
I used the shopbot to cut out the shape of the shoes and the strap cut outs.
Step 3: Make It Wearable / Adding the Strap
I used a piece of burlap as the strap, but you can make this out of plastic sting or anything that feels comfortable on your feet. I started from the center hole pulling the burlap down below the shoes, them apply hot glue to secure them in position. I made sure that as I am pulling up, some of the hot glue carries to the top of the hole for better hold. I then measure the length of the strap to make sure that my feet fits comfortably.
Step 4: Customized / Laser Engrave
I used Katsushika Hokusai as pattern for my shoes, I made the drawing into vector for laser cutting. The engraving added extra grip but it might feel a little uncomfortable. I guess we can use clear resign to make the surface flat for not etching it too deep with the laser.
I vectorized the Katsushika Hokusai's The Great Wave off Kanagawa drawing with Illustrator, I then mirror the pattern for the right and left shoes.
Step 5: Casting the Rubber Feet
The wooden sandal makes a lot of noise around the studio, so I decided to add rubber to the feet. I used MOLD MAX 60 part A and part B to make the rubber. They take about 24 hours to cure.
I hot glued temporary fences to contain the rubber casting material, so I can pour the rubber without leaks.
Once it’s cured, it’s ready to perform, without loud walking noises.
Step 6: Thoughts
The down side of the sandal is that it’s a bit heavy but does the trick.
