The Boost Rings are large rings that encircle the entire roads they are found on, with the roads resting on their inner rim. Their outer rim is segmented by recesses and their inner rim glows cyan. However, the coloring of their outer rim depends on the level they are found in.
The Boost Rings are located exclusively in the speed sections of the game. When the playable characters passes through one, it will briefly flash cyan and give the playable characters a sudden and straightforward increase in running speed.
