The Seac Motus Long Blade Freediving Fins are designed to deliver outstanding comfort, powerful propulsion, and exceptional efficiency for freedivers and spearfishers of all experience levels. Combining an ergonomic full-foot pocket with a high-performance interchangeable blade, these fins provide smooth, effortless kicking and reliable performance during extended underwater sessions.

The advanced 22° blade angle naturally aligns with the leg's movement, maximizing thrust while reducing strain on the ankles and calves. This efficient design allows divers to conserve energy, making the Seac Motus an excellent choice for freediving, spearfishing, dynamic apnea training, and recreational diving.

Its innovative dual-density thermoplastic foot pocket features a rigid sole for efficient power transfer and a softer upper section for superior comfort and a secure fit. The closed-foot design can be worn barefoot or with 2–3 mm neoprene socks, providing versatility for different water temperatures and diving conditions.

One of the standout features of the Seac Motus is its interchangeable technopolymer blade, allowing divers to easily replace or upgrade blades to suit different diving environments or personal preferences. The highly responsive blade offers excellent flexibility and propulsion, making every kick more efficient while minimizing fatigue during long dives.

Available in a wide range of sizes for both men and women, the Seac Motus is a trusted choice for underwater hunters, freedivers, and serious training enthusiasts seeking comfort, durability, and high-performance finning.

Great value pretty comparable to the $150 crusty softer blades

These were really comfortable with booties. Appreciated the flexibility and they were a great deal (I got them on sale)

SEAC Motus Size - Black - 11.2 Shoe Size - US

These definitely run on the large side, unless you are going to wear very thick neoprene 3-5 mm socks. I steeped down one Size to the 9.5-10 US and used the cresci ultra stretchy socks; the fins fit perfect. The foot pockets are comfortable as others have reported. I also like that I can switch out the blades in the future.

Great long fins

Firstly, I need to qualify that I have been using scuba fins my whole life and had no issues. As I am getting into free diving with friends and lost my scuba fins, I purchased these on amazon a few months ago. I have used them only 5 times but love them. I wish I had gotten longfins years ago. They feel much better underwater than scuba fins. They are very stiff and feel sturdy. One comment is that they rub a little bit but I think that is unavoidable for all fins without booties.

Ferrari of the Sea Despite Battle Blisters

I'm generally a size 9 ½ or 10, & the 8.5s are still a little big. It was my hope that I'd be able to wear these without having to also spend on boots, but initial testing chafed around my Achilles tendon, & my ring toe developed a battle blister. Wound up using two ankle high socks on each foot to solve the issue. As an ignorant & inexperienced young freediver I took these fins to practice in the 6' deep community pool for several days. The fins have gotten scraped & frayed along the edges, nevertheless the material held up incredibly well. By comparison, these babies are the Ferrari of the sea. Despite how exhausted, burned, or blistered I am, I'm always sad to take them off.

Not bad

They are good, but a little heavy and stiff, and you need strong legs to swim with them for long distances.
