Photoshopfail? What is wrong with the picture?

https://www.google.de/...J4iv-8EfM:. I do not see the mistake?

The lady with crossed legs has 2 right feet, which is likely to cause problems when buying a shoe…

It even stands in the title:-)

She has two right feet, look at the big toe.

I do not see a problem there. Just buy two pairs and throw away the left shoes ;-)

Or give to someone who has two left feet.

Right.
