Shoe shop

Does anyone know of a good shoe shop in Taipei - in particular one that does kids shoes? My definition of good is:
*) They have the ability to measure your feet
*) They understand the concept that some feet are wider than others
When I was back in the UK buying shoes for my son the attendent spent about half an hour measuring his feet, trying on different sizes, and lecturing me on how important the right shoes are for growing feet. In Taiwan, the best shops I can find have attendents who will happily tell me he looks “hao ke ai” in a particular pair - but that’s about it.
