In the world of comics there are some things that are just a given. Those ankle wings that Namor has that enable him to fly have always been a big part of what makes the character and he’s used it as a powerful tool throughout his printed history. They’ve never been under or overplayed.
They allow Namor to travel quickly through the air as well as to swim at superhuman speeds. They’ve also allowed him to take on water based forms and to manipulate aquatic environments to his advantage. They’ve also aided him in his ability to project energy and in his telepathic abilities.
In one of the earliest examples, Namor was facing down a squad of Sentinels that were sent by S.H.I.E.L.D to usurp his throne. While he could have easily thrown himself into the ocean to avoid them, Namor decided to flex his muscles instead. His ankle wings aided him in this by allowing him to distribute his weight and likely amplify his strength, tearing the Sentinels apart.
This is one of the earliest examples of how powerful Namor can be when using his flying ability. He’s been shown to be able to outpace some of the best that Marvel has to offer and this is just another example of how fast he can fly. Storm is rated faster than him in the handbooks but until we see Namor outpace her or they have a direct confrontation its hard to say for sure who’s faster.
