toe walking and braces

My son is 7 and has always walked on his toes. He had been seen twice
by an orthopedic Dr. and once by a neurologist in the past and they all
said he had OK range of motion and to wait for him to outgrow it. Last
week we had to visit the ortho dr. because he broke his arm and I had
them look at his feet again. Now the Dr. says he needs to wear braces.
Obviously I'm very worried about this. A search on the internet has
revealed a wide variety of worrying options such as casts, surgery, and
braces. We are going to get a second opinion.

Any advice and ideas on this problem ? Also any advice on how we can
approach this with our son - as I'm sure he will not be enjoying the
experience of wearing braces (esp in the summer).

Thanks!
