Do you mean bespoke shoes? You're going to pay big for those. Not sure if you're male or female, but being male all I know is shoes for men, where bespoke shoes will cost you (starting) in the region of GB£1,000 from the likes of [broken link removed], [broken link removed] or [broken link removed].

In answer to your question, I don't think there are any bespoke shoemakers left in Dublin, but as you can see from the links above the industry is thriving in London and Northampton.
