Split fins reduce effort by 40%. Blade fins offer greater propulsion. Discover material and type for your diving style.
Fins are one of the pieces of equipment that generate the most debate among divers of all levels. Sizing questions, model comparisons, and home modifications such as adding springs for better performance are all discussed. Northern divers concerned about fins that work well with thick booties generate specific questions that are not always easily answered by technical data sheets.
Full-blade fins offer greater propulsion in current and allow advanced techniques such as the frog kick, being preferred in technical diving; split fins reduce muscular effort by up to 40% thanks to the central slot. In terms of material, rubber blades are heavier but transmit force better, while carbon fiber blades offer maximum efficiency at the cost of greater fragility. Open-heel fins are the standard option for cold water with booties, while full-foot fins are reserved for warm water. Maintenance consists of rinsing with fresh water and storing flat away from sunlight.
