In coastal dive centers, where equipment is exposed daily to the corrosive effects of salt and sun, durability and versatility are primary selection criteria for instructors. The Japanese manufacturer Tusa offers the SF-22 Solla fin, an adjustable fin known for its longevity and performance in temperate waters. We analyze its features objectively to help you make your future purchase.
This detailed evaluation report is based on our documentary analysis conducted on August 6, 2026. Our ranking system maintains its neutrality, and no affiliated links are active on our website.
To analyze the effectiveness of this two-material design in a standardized manner, we evaluate it based on five criteria with equal weighting. No field tests were conducted by us for this particular design. This overall score of 4.15 out of 5 represents its theoretical design quality and does not guarantee individual comfort.
The Tusa SF-22 Solla is an adjustable fin designed for recreational scuba diving and marine exploration. Its open heel design comfortably accommodates booties with soles.
Its robust design makes it an essential reference for many clubs looking to equip themselves reliably. Its responsive sail is perfectly suited for intermediate divers seeking consistent thrust, with a medium weight of 850g.
The sail incorporates the patented ForcElast technology with flexible channels and a 20-degree angle to reduce fatigue. This design allows for an excellent "flutter kick" propulsion style with very good efficiency.
Imagine a rower training with polymer-reinforced oars, where the handle bends to store energy before releasing it at the end of the stroke. This controlled flex allows for optimal hull glide on the water without jolting the back. This adjustable sail utilizes ForcElast channels that return the energy from each stroke. The frog kick and back kick styles remain effective underwater.
The ergonomic thermoplastic rubber cuff snugly wraps around the boot without creating painful friction. The anatomical strap ensures a perfect fit during each stage of paddling.
Muscle fatigue is reduced thanks to the angle of the sail, which protects the ankle from painful twists. The comfort of putting on and taking off these shoes remains highly appreciated in this flagship model from the Japanese brand.
The assembly combines durable polypropylene for the longitudinal supports and soft TPR for the elastic push channels. The fin has a neutral buoyancy in seawater to maintain good body alignment.
The composite materials are resistant to prolonged exposure to sunlight and salt water without deformation. The shape memory properties of the ForcElast channels prevent any loss of power over the years.
The reinforcements on the lateral ribs effectively protect the sail from impacts against corals or boat hulls. The patented EZ quick loops make it easy to adjust the strap.
The sole is textured to provide reassuring grip on slippery surfaces such as boat ladders or wet decks. The durability of this model makes it an excellent long-term investment.
The table below classifies the suitability of the Tusa SF-22 Solla based on your usage profile:
| Diver Profile | Verdict and Usage Recommendations |
|---|---|
| Intermediate Diver | Excellent, the performance and ease of putting on are perfect. |
| Club Diver | Ideal, the robust construction can easily withstand heavy use. |
| Cold Water Diver | Very suitable, the adjustable bootie accommodates thick socks easily. |
| Ultralight Traveler | Fair, the weight of 850g per fin requires a well-sized travel bag. |
The Tusa SF-22 Solla is an essential reference for regular divers and dive clubs. Its efficient ForcElast propulsion system and legendary robustness justify its very good overall rating.
