Dual Durometers are very unique, with each color combination having its own unique feel based on the different materials used for each colorway and their differing density! They also have that iconic look. Performance wise, these are extremely popular, with a wide shape that is slightly shorter than G4 wheels. A FlatFace original creation since 2013! Please note that a small amount of movement between the inner and outer core is normal and is part of our secret sauce and why they feel so smooth and special!
