Labrax Boom Fibreglass Fins (Pair) Medium are fantastic value complete spearfishing or freediving fins. They feature new ultra light thermoplastic "Boom" foot pockets fitted with a pair of green camo patterned blades, in medium hardness.

High performance tough composite blades are soft on the legs and good for oxygen efficiency. Super light and flexible fibreglass blades marry perfectly with the footpockets.

Footpocket weight is around 500g with a 22-degree heel angle for optimum performance and comfort.

Side tendons slide over t-rails on fin blades and fins are then screw fixed with orange toe plates and clips over the tendons, complimenting the orange highlights on the blade branding.

The shape and feel of these pockets provides excellent comfort to the wearer. The hard soles ensure maximum transfer of power to and from the blades. These 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.

Please check out the examples below for the sizing selection.

A. If your foot size is EU40 and using 5-7mm socks, please choose Size 41-42
