I bought this to replace the soles of my Birkenstock sandals myself, but I ended up not using it, so I'm selling it. It has the same design as the soles used on Birkenstock Arizona sandals, and it seems to be a standard material for making huaraches. If you're using it for Birkenstocks, it's difficult to DIY unless the upper is cork material, as the border with the sole will be hard to distinguish.
