My daughter has used AFO's since she was born...she is now 6 years old. We have looked into Hatchbacks...cute but yes, they are expensive.
For the age of your daughter I would suggest asking your orthotics person if they carry "Answer 2" shoes. As with Hatchbacks, they are specifically made for AFO's...they are wider and deeper than regular shoes...and look like regular tennis shoes...little ones also light up when they walk.
Answer 2's do carry black Maryjanes "dress" shoes, but I think they start at size 11. "Answer 2" shoes are very easy to get on. Also look into Stride Rite shoes...a lot of our friends have found that they work also.
Good luck and have fun with the braces. We always celebrate our new braces and have lots of fun picking out what design we want on them.
Feel free to contact me if you have any other questions.
