Speedo DMC Super Fins - Blue

Stand on a piece of paper with your toe against a wall. Mark the end of your heel at the achilles arch — this is where the fin strap sits. Measure from the wall to your mark in millimetres. This should be approximately 3–5mm less than your full foot length. Use this measurement to find your fin size in the table above. If you fall between sizes, choose the larger size.

If your foot length falls between two sizes, always size up. Fins that are too tight can cause blisters, cramp, and discomfort during training. The silicone material will bed in slightly with use and mould to the shape of your foot over time. Speak to a member of staff at Allens if you are unsure.

Rinse the fins thoroughly in clean fresh water after every use to remove chlorine, salt, and debris. Store flat in a cool, dry location away from direct sunlight. Do not fold or crease the blade during storage. Avoid walking on rough surfaces such as pool surrounds or concrete as this can damage the fin blade and silicone material.

DMC fins can be used in both pool and open water environments. However, they are primarily designed for pool training and bodysurfing. Always ensure fins are properly secured before entering open water, and avoid walking on sand or rough surfaces which can accelerate wear on the silicone blade.

No. The DMC Super Fin has a universal foot cavity, meaning either fin can be worn on either foot. This makes them quick and easy to put on and remove during transitions from deck to pool or sand to sea, and provides a wider foot cavity suitable for a broad range of foot shapes.

SILFORM is DMC's proprietary silicone-based material. Compared to standard silicone, SILFORM is softer and more flexible, providing maximum comfort and reducing fatigue during extended use. It is particularly well suited to fitness swimmers and bodysurfers who wear fins for longer periods and need a material that cushions the foot without sacrificing propulsion.

Yes. The Super Fin is available from 5XS (approximately EU 27 / UK 5.5–7.5 Junior), making it suitable for children from around age 5 upwards. Always measure foot length rather than relying on age or shoe size. The universal foot cavity and soft SILFORM construction make it a very comfortable choice for younger swimmers and those new to training fins.

The Super Fin uses softer SILFORM material and RVR technology with a universal cavity — it is the most versatile and comfortable fin in the range, ideal for fitness swimming and bodysurfing. The Original Fin is firmer with a closed heel pocket for lap swimmers. The Elite uses a V Rail design for competitive swimmers. The Elite Max is the most performance-oriented with RVR technology and a left/right specific cavity for maximum speed.
