Neptune had Neptune blue laces, that's obvious. FYI Neptune and Poseidon, are in the same boat. How did the God of the seas conquer the seas, if not? Highly regarded in the Mediterranean and elsewhere, these Neptune blue laces give an aquatic colour to your feet.
Poseidon and Amphitrite, according to the myth (I checked and this story was of course erased) started under the recommendation of Prometheus to make Neptune blue laces but this production stopped because Zeus, jealous as he was, struck everything down..
