Air Gear
In the world of sports manga, Air Gear is an outlier. While not grounded in reality, Air Gear highlights rollerblading in an over-the-top, absurd, best-way-possible kind of way, so while it's not necessarily an accurate representation of the sport, it's an exciting read that takes rollerblading to a whole new level with the introduction of futuristic motorized rollerblades called Air Treks.
This, of course, raises the question of whether Air Gear is, in fact, a sports manga, There are many series that exaggerate a sport or the players' abilities to play that sport in order to make it feel larger-than-life, and I believe Air Gear is just a more advanced version of this.
The competitions in this series are thrilling, as you watch the characters perform daring stunts and overcome seemingly impossible obstacles. Because of the aggressive nature of the competitions, this one feels a lot like a battle shonen at times. It's also an ecchi manga, making it one of the best action ecchi manga you can read, so it has something for everyone!
