I'd actually consider that. It'd depend on the shoes and the price. At present, I'm running about 1,500km a year. My shoes are $260 (unless I can find them on sale) and I get around 1,000km out of each pair. That works out at around $10-15 per week on shoes.
I doubt whoever is renting shoes out is charging that much for the service.
What about the power cost of all the internet infrastructure and servers needed to deliver the content vs a bit of polycarbonate and aluminum that you can play whenever you want using a player and TV?
