I have a size 14 1/2 foot. My feet do not fit entirely on the Wii Fit balance board. Either my heel hangs over or my toes or both, depending on exactly where I stand on the board. Is their a Wii Fit balance board adapter for larger feet? Does Nintendo plan to come out with a large balance board option or a fit-on adapter for larger feet?

I too would like to see a larger balance board. I'm toxically injured and after an exposure, I swell up to 5 sizes. The edema/lymphedema makes it impossible to stand with your feet together... I've been using my wii fit & plus to rehabilitate for two years now. A wider board would be great. It makes sense that they should make different sizes, not everyone is appropriately sized for the standard board.

that would be nice. My toes and heels go almost exactly to the ends of the board and I'm always adjusting my stance.

There are now two wii fit boards, one is white (basic) other is blue,
well it is here in NZ the blue one is more advance with a scale for weights, etc.
Looks quite good. Hope that helps a bit. Maybe do a search and it might come up.
