The Shape Belt is an item in which Shapes can appear and make items. Geo wears the Shape Belt around his waist.
It can make any shape that become building blocks that Geo can use to make anything. He adds the right shapes to blue prints then brings them to life with his Shape Powers.
It's unknown if Geo built the Shape Belt or someone else did.
In Team Umizoomi VS. The Shape Bandit, the Shape Bandit stole the Shape Belt from Geo. He was not able to instantly make shapes, but Geo used object shapes around him to make things that can help catch the Shape Bandit. After the Shape Bandit returns all the shapes, he gives back Geo's shape belt, and apologizes for taking it.
Geo will ask the viewer to say the name of the shapes needed to build something. Then he will say "Super Shapes!".
- The Shape Belt is a source of Geo's power. (As Proved the fact that Geo constantly has a Blue Print in the background of the thing that he/the viewer has to build)
