Tinkerbell Half Meet Up in January 2013 at Disneyland - they gave away 4 pairs of these via name drawings while we were at the meet up. For the drawing portion I was sitting at a table with 2 very nice girls I had met from the #rundisney facebook page. Both of them were drawn for a pair of these shoes... me? Nada.
HERE is a fun video of how New balance came up with the concept and design of these shoes for runDisney.
As far as I know the only way to purchase these wildly popluar shoes is to attend a runDisney evet and get in line... say a prayer and maybe you will be able to purchase them (I believe they are about $125). The only other way is to go on EBAY, bid on a pair, and end up paying WAY more than the New Balance price.
