Sounds like a future art project!
I was just going to post a size 7 Jackson Premiere that were custom ordered with a size E toe box and AA heel. It's a pretty drastic split width size, I was going to ask $75 OBO + shipping for them. Not sure if those would work but I thought that was a reasonable price. They were only worn for about 4 months.
Interestingly, we currently have a Harlick 7.5 (also for sale), Jackson 7, and Riedell 6 and they are all roughly the same length, each with the e/aa split width. I wish sizing were a more standardized, it would be so much easier! Also, for the first time ever, we met another girl at the rink with the same crazy foot shape which we affectionately call "duck feet".
