The whole barefoot thing makes sense to me but then I got admonished by a 'traditional' shoe fitter for considering an unstructured shoe for our toddler. Doesn't a structured shoe, rather than 'support the foot', just mould the foot to the shoe and restrict foot movement? Or have I believed the hype 
We have a history of wonky feet/knees/hips etc in our family, so I'm keen we don't make things worse.
Is barefoot just a fad? Any podiatrists out there that settle the debate?
