My first thought is wooden shoes like clogs or those Japanese sandals. Of course neither of those are practical. The only BFL shoes I can think of would be made of some hard inflexible material which would be very uncomfortable. I think leather would provide the best wear. I used to exclusively wear adidas sambas. They'd last a few years with the only real issue being the souls getting worn out. Now I have steel toed boots for work which are a whole other level of wear.

How is the seam where the two half's connect? Cheap plastic tends bend or warp over time so that they don't line up. Does it have something interlocking like tounge and groove?

How many phone calls to get the video call up and running?

I'd take them because there are a lot of useful parts. Repairing them might be pricey but will probably be worth it for their size
