Labrax Boom Fins (Pair) are new ultra light spearfishing and freediving fins, featuring thermoplastic foot pockets and black fin blades.

These have a 22-degree heel angle these for the optimum balance of performance underwater and for surface intervals as well. Great all-rounder two piece fin for all from newbies to advanced, allowing an easy upgrade of blades to fibreglass or carbon in the future.

Side tendons slide over t-rails on fin blades and fins are then screw fixed with toe plates and clips over the tendons. Fixing kits provided are red in colour, complimenting the red and white on the fin blade logo. Other coloured fixing kits are available separately, if required.

The shape and feel of the footpockets provides excellent comfort to the wearer. The hard soles ensure maximum transfer of power to and from the blades. Footpockets carry a 24 month warranty against manufacturing faults.

These fin footpockets are made roomy, to allow the use thick neoprene socks up to 7mm. They will fit a large range of foot widths by adjusting the choice of socks. So if wearing with thicker socks, choose the size that corresponds with your foot. If not wearing socks, we recommend choosing a size down from your normal shoe size.
