Wood or synthetic foam was formerly used as the limb core. However, the INNO Power limb adds Kevlar hybrid foam at regular intervals in order to maximize both materials' advantages. In the case of a wood core system, the features offer superb tolerance due to the fibres and it's high adhesive propert. However, it is heavy, weak in humid weather, and due to knots in the fibres causes limb twists.
Contrary to the wood limbs, synthetic foam core features lightness and strength against humidity. However it is brittle plus the adhesive property is weak which results in weakness of limb endurance. Kevlar hybrid foam is the new core that has both merits of wood and foam. This new material reduces limb twist and increases limb endurance as well as keeping all the advantages of superb tolerance, high adhesive properties, light and consistency in humidity
