Today's side by side REAL VS REPLICA op-ed: Nike SB Dunk Low StrangeLove Skateboards (CT2552-800). 

Authentic SB Dunk Strangelove have a more sophisticated insole, while the replica uses liberally a textured inlay. 

The real shoe also has uneven colored patches on the insole, which is a result of the special glue used. The replica has a clean, even finish, meaning it probably did not use glue or the same type of glue.

The air cushions on the back of the insole are also built differently. The real shoe has a cushion made up of three separate parts (two small rectangles and a circle), whereas the air cushion on the replica is just one rectangular piece.
