Hmm, but they may be small sizes, but they still require labour to manufacture and then retail costs to sell. How much would you expect shoes for infants to cost? At what quality and at what conditions for the workers? Admittedly I don't know anything about Clarks' production conditions.
I'll admit that these look expensive for what they are. I don't really 'get' crepe soles - they don't look that durable or like they provide a good grip, and they have a weird smell, at least when new.
