Edit: to clarify, I do know that if shoes are cheap they're likely to be made by children and that ethically made shoes will be more expensive. However, labour costs aren't the only thing that determines the price, material costs are a thing as well. (And companies would love us to think that this factor is the main deciding one because they can't really skimp on that without losing quality, now can they?) So my thought process was that these shoes made from trash presumably have lower material costs than conventional ones that are made ethically from non-trash materials so shouldn't they be cheaper?
All I know is I have a hard time justifying 120 € shoes, no matter how and from what they're made.
