Nice big fins


I ordered the EU size 40-42 in combination with an EU size 40 Aqualung Superzip Ergo Elite 5mm boots. The fins themselves are nicely designed and come with a fairly large foot pocket. For the Aqualung superzip ergo EU size 40 boots, those foot pockets are a bit too big to my taste. This is especially the case in combination with the rubber straps as it can feel a bit loose. However, when in use, the finnish didn´t came off. A nice touch of the rubber straps is the large rubber whole plate with a big hole which fits gloved fingers. The blades themselves are quite sturdy near and around the foot pocket and become gradually more flexible towards the tip. When tested in a big lake with no current, it was easier to use the frog kick with this finnish instead of the flutter kick.

Great fin!


Great fin! Fast delivery! Top price!

Great fin!


The delivery was really fast! Price is top! With the color everyone sees me under water ;-)

Top fins


Had ordered the fins first for snorkeling. Nice propulsion, not too hard blade. For my girlfriend, petite a good fin. Even when diving she makes the same figure. Are very satisfied

Perfect purchase


Fins of very good quality ... the perfect wedge size (37eu) The system of the heel coupling is very comfortable. I chose them because it combines perfectly with the Seacsub Fox mask. Arrival time to Chile of approximately 1 month. Excellent store!

Seac f1 s - size with boots ??


I am about to order some open heel fins, but a question came up. You have always overused fins with foot pockets, and att is pretty easy-to get the size right. I am a size 42-43 so I shouldnt get enten the Seac Basic HD 5mm (size Large) - or Cressi Ultra Span Boot 5mm (size Large) to go with the fins. Regards Thomas
