I have another pair of New Balance in 9.5 wide.  While I know different styles can vary, this 9.5 wide was very narrow.  Come on NB and Disney, not everyone has a delicate Cinderella foot!  Still, I gave the shoes a mini trial run for about 1 min on my home treadmill.  I found the soles of the shoes to be very slick.  I did love the style with the cute Minnie Mouse details and was so disappointed it didn't work out.
