In gameplay, the Boost is a technique that not only allows the player to run at vastly increased speeds for as long as the move is active, but also to damage and/or destroy enemies and breakable obstacles by simply running into them during the Boost, all without taking damage or slowing down. The latter empowerment enables the user to fling Meteorite fragments at their opponents with extreme accuracy. Additionally, the Boost can be enhanced further to increase its power through Super States or Energy Cores. Shadow, on the other hand, spears ahead while enveloped in his own energy field, hovering above the ground while using his Air Shoes to propel himself forward.

Sonic, for example, simply runs along the ground in an aerodynamic pose while enveloped in the Boost's energy field. The execution of the Boost differs slightly between users.

While using this move, the user is able to barge straight through obstacles at staggering speeds without slowing down. The color of the energy field depends on the user: Sonic's is (usually) blue, Shadow's is orange-yellow, Classic Sonic's is light blue, and the Avatar's is white. When performing the Boost, the user surrounds themselves in a projectile-shaped energy shield and propels themselves forward at speeds beyond the sound barrier, thus turning the user into a highly destructive projectile moving at supersonic speeds.

In Sonic Unleashed, the technique was finally fleshed out for the consoles, drawing much of its content and dynamic from its Sonic Rush series counterparts. It was later implemented into Sonic Rush and Sonic Rush Adventure, where the technique was redeveloped for universal usage and dubbed the "Super Boost." Sonic the Hedgehog (2006) would later develop an exact picture of the mechanism, a technique which subsequently appeared in Sonic and the Secret Rings.

The concept of the "Sonic Boost" was first introduced in Sonic Heroes, where any character could repeatedly use a short momentary "Dash" of speed in the Special Stages.
