Agua is a very easy-to-use fin. It does not require any special athletic water sports skills to snorkel and dive with this fin. Nevertheless, it offers excellent performance without tiring the feet. Thanks to the latest technologies and Cressi's experience, the development of these products has succeeded in noticeably reducing the weight compared to a fin of the same category while still maintaining outstanding responsiveness. The shoe is equipped with the innovative Self Adjusting Foot Pocket System, which guarantees a consistently comfortable and snug fit due to the special softness and elasticity of the material blends.
