Truly high-heeled ones are pretty much impossible to find pre-made unless you have $$$$ to spend.
You'd have to make them yourself, but if you have access to power tools it shouldn't be too hard.
The closest available would be maiko style geta, which are called okobo or pokkuri geta, which you can sometimes find on ebay. They don't have the gap in the middle, but they're pretty high. They can be fairly expensive though.
