Here's a really nice pair of hard Irish dance shoes in size 5-1/2, never worn and just waiting for someone to dance in them!  As you can see from the pictures, they look perfect except that the leather insole has curled a bit, which must have happened in storage.  I bought these in 2000 and thought I would be going on in Irish dance lessons but alas, I haven't!  But you can!!  :)  I'm unaware of what else you'd need to know about these except maybe that the sole feels nice and flexible and it's really nice leather.  I wear a size 7.5 shoe so the sizing on jig shoes must be different.  Please contact me if there's anything else I can tell you about the shoes!  No-reserve auction, low shipping, these could be yours for a wonderful price!  Easy return if you need a different size.  Thanks for looking!
