Because… agility needs power, power needs control and accuracy needs to be delivered with efficiency.
Careful blade design both increases power and maneuverability.
Traditional rubber can harden in low temperatures, soften in high - not the tough material in the EX1 fins though - consistently high performing.
3 different fin stiffness levels means you can choose a fin for your exact needs.
Softer material in the upper footpocket prevents drysuit boot wear and is much more comfortable.
Our understanding of materials technology has allowed us to break away from the old style, albeit iconic 100% rubber mouldings and to deliver a softer material in the entry part of the foot pocket. This enhances feel and thereby control. In addition it is more comfortable, whether on a long swim or against a tough current.
Rubber fins in warm water or left in the sun can soften, immersed in cold they will stiffen up. You may as well be diving different fins! By using an advanced techno-polymer instead of rubber, whatever the temperature the EX1 fins will give you the same familiar feel throughout the dive.
