Stride Rites are good, but ridiculously expensive. a basic pair will cost about $38-50 dollars. However, the same factory hat makes stride rites also makes the Sure Fits from Payless. We've bought both from our son (who has a really wide foot). They may not last quite as long as he brand name, but their feet grow so fast at that age, that he probably won't wear them out before growing out of them.
You can find used shoes at Once Upon A Child, but sometimes I'm shocked at the condition of items they resell.
I'd go for payless! We also get decent shoes at Target too and sometimes Kohls.
