The lively string for dynamic offensive tennis
Every shot causes a real fibre storm inside the Isospeed Energetic which descends directly onto your opponent.
As with the Isospeed Control, the Energetic relies on the free swinging power of the ribbons in the string core. Thanks to the material mix of polyester and polyamine the Energetic also provokes exciting inner workings. The fibres have free movement among each other and create additional energy. This is off loaded in every one of your strokes! Also in the matter of control, comfort and durability, thanks to proven Isospeed technology the Energetic cannot be faulted.
Benefit from the powerful acceleration of the Isospeed Energetic.
