Bikes and cars are modes of transport. They're optimal for getting around at high speeds, but when you don't need them, you need to leave them somewhere, they're large and not very convenient. On the other hand, these are shoes. You put them on in the morning and can wear them anywhere outside, they're not separate things you need to handle. I can definitely see demand for this from people who walk all day long for their jobs (warehouse workers, military, etc) or hikers/runners who want to stretch their endurance over a larger distance.

For that matter, I could see walking more if this kind of assist meant that more places are suddenly within walking range now in terms of one's capacity to get there without exhausting oneself.
