Delta compatible shoes and KEO pedals I am planning to by these cycling shoes which claims "Restriction of use:Only compatible with Delta Pedals and Cleats". 

Reading up about Delta and Keo I understand that Keo pedals and Delta cleats are not compatible and vice versa. However, I could not find if the Keo cleats can be fit on these shoes. 

So I guess my question is, if I buy these shoes and Keo pedals+cleats, can I fit the 3-hole Keo cleats on to the 3-holes in the shoes? In other words, are the dimensions and size of the 3-holes same in Keo and Delta?

Hope I make sense. Thanks!
Hole positions for Keo and Delta are exactly the same. I've switched over 3 years ago and the shoes didn't cause any problem.Even Shimano cleats of the 3-hole type have exactly the same pattern for the holes. And with the adapter Speedplay cleats will fit too.
