The Spike Traps have the same basic appearance of that of the Weights, which is a large, black and rectangular metallic block with a red line along its edges. Unlike the Weights however, they have Spikes on their bottom surface.
The Weights can moves up and down automatically in intervals. Some of them fall down instantly while others take their time. When they are about to fall, the red outline on them flashes. Filling the role of obstacles, the player will take damage should the Spike Traps fall down on Sonic or if their spikes touches him, though they will not make the player lose a 1-Up like the Crushers. Alternatively, the player can climb on top of Spike Traps as they rise, which makes them work like rising and falling platforms.
In the Wii version of Sonic Colors, and the remaster Sonic Colors: Ultimate, the Spike Traps appear in the Sonic Simulator, where they keep moving slowly toward the player when they are in front of them. In this game, they are in horizontal form.
