I had another idea on this awhile back but never followed through. I wanted to try Irish soft shoes. They are cute. I found a type which seemed to be ideal - Hullachan Pro. Only, you have to get someone to fit you (ideally). If you read the testimonials they seem great. Not too many dealers around tho. I may eventually just try to order them directly.
