i agree with cara, soft soles and not proper shoes for at least 6 weeks after they start walking by themselves. I'm not sure what is available in HK - I like Clarks from Australia, StrideRite from the States...sorry I can't recommend any shops...
I used soft soled shoes (robeez) when we went to in indoor playground or something similar, hard soled shoes once they were actually walking independantly and walking outside over 1 year for my children) and at home, bare feet or socks.
recent studies suggest that wearing shoes except to protect the feet causes gait problems and discourages the normal development of the foot, so babies anf kids should only wear shoes outside/when walking somewhere they may hurt their feet. I know it was in the wall st journal and I'll look for some links if I have time today.
