Pretty much guaranteed to be fake. A book like that would not be practical in any way. As you see, even reading it would require stupendous arm muscles after the first couple feet.
A Google Googles search turns up a lot of hits with this phrase "Manual Para Entender as Mulheres": "Manual for Understanding Women". Another reason to believe the photo is a fake. The book is far too small for the purpose, well, unless it's only one volume of of the complete set, which I hear is stalled at twelve volumes as publishers argue over the appropriate response to "Will you please pull over and ask for directions?"
The entire project is, of course, a complete waste of time. Everyone knows that men don't read the manual.
But, to keep on topic, what am I doing now? I'm ducking of course, in case shoes really can be digitized and thrown thrown across the internet.
