If they're using PLA or ABS, I don't think footwear usable due to comfort. (ABS is the same plastic that Legos are made of, so imagine how inflexible they would be, and PLA is going to be similar) Given that the build envelope is only 5.5 cubic inches, I also don't think you could actually make adult size footwear.
