Product Information
The Tusa Solla Full Foot Fin (FF-23) is the full-foot version of TUSA's SF-22 Solla, built with the brand's ForcElast technology and a patented 20° Angled Blade Design for efficient propulsion. It is designed for any diving style and ships in sizes XS through XL.
Who it is for
The FF-23 suits divers who prefer a full-foot fin, slipping on bare skin or a thin sock rather than over a boot. TUSA classifies it for any diving style, so it suits general recreational diving where a boot-free setup is preferred.
Key details
The Solla full-foot fin is built around three core design elements that drive its performance:
- ForcElast technology: a proprietary thermoplastic elastomer compound placed precisely in the blade and foot pocket structure to deliver propulsion and efficiency with moderate power input.
- 20° Angled Blade Design (A.B.D.): TUSA's patented blade angle accommodates the diver's anatomy to ensure maximum efficiency throughout the kicking cycle.
- Three-channel blade with crescent tip: channels the blade with reinforced side-rails and vents to fine-tune performance and maximize propulsion.
Compatibility and sizing
This full-foot fin is sold in sizes XS, S, M, ML, L, and XL, with no boot required since the anatomically designed foot pocket is worn directly against bare feet or a thin sock.

Frequently Asked Questions
What is the difference between open-heel and full-foot fins?
Open-heel fins have an adjustable heel strap and are worn with dive boots, which protect your feet on shore entries and add warmth. Full-foot fins slip on like a shoe against bare skin or a thin sock, and are typically lighter and easier to pack. Most scuba divers choose open-heel fins with boots, while full-foot fins suit warm water, snorkeling, and pool use.
How should scuba fins fit?
Open-heel fins should be sized around the boots you will actually wear, snug with the strap set so your heel stays seated and your foot does not slide forward in the pocket. Full-foot fins should fit like a firm shoe, with no heel lift, no pinched toes, and no gap that lets water pump in and out. Too loose causes heel blisters and lost fins in current, and too tight causes foot cramps.
Should I buy dive boots before fins?
Choose your boots first and size open-heel fins around them, because sole thickness changes the foot-pocket size you need. A thin warm-water boot and a thick cold-water boot with a rugged sole can easily be a fin size apart. If you already own fins, bring them along when you buy boots so you can check the combination.
Are spring straps worth it?
Spring straps replace the adjustable rubber strap with a stainless spring that stretches on and off, so there is nothing to buckle with cold or gloved hands and no rubber strap to perish and snap mid-dive. They hold constant tension, which many divers find more comfortable and consistent. They are sized rather than adjustable, so match the length to your foot pocket and the boots you dive.
What are the best fins for travel?
For travel, length and weight matter most, so shorter blades and travel-specific open-heel or full-foot models pack more easily and save baggage allowance. Some fins have removable blades or compact foot pockets designed for luggage. Pack fins along the outside walls of your bag, where they also act as protection for softer gear.
What is the difference between paddle and split fins?
Paddle fins use a solid blade that transfers power directly, which many divers prefer for precision, control in current, and non-flutter kicks such as the frog kick. Split fins have a slit down the blade that lets water pass through, which generally makes flutter kicking easier on the legs but gives up some control and works less well with other kick styles. Neither is inherently better, so let your kick style, leg strength, and conditions decide, and try both if you get the chance.
How do I care for dive fins?
Rinse them in fresh water after each dive day, paying attention to buckles, springs, and strap channels where salt collects, and dry them out of direct sunlight. Store them flat or hanging from the foot pocket rather than standing on the blade tips, which can take a permanent bend. Check straps, buckles, and any screws before every trip, since a failed buckle is the most common fin problem.
What sizes does the Tusa Solla full-foot fin come in?
The Tusa Solla FF-23 full-foot fin is offered in six sizes: XS, S, M, ML, L, and XL. Since it is a full-foot fin, it is worn directly against bare skin or a thin sock rather than over a dive boot, so size is chosen by foot fit rather than boot thickness. If you are between sizes, call or chat with us for help picking the right one.
What is the difference between the Tusa SF-22 and the FF-23 Solla fin?
The FF-23 is the full-foot version of TUSA's SF-22 Solla and uses a newly designed anatomic foot pocket.
What type of diving is the Tusa Solla full-foot fin designed for?
TUSA classifies the Solla FF-23 as suitable for any diving style, meaning it is not limited to a single discipline like freediving or scuba. Its ForcElast blade and angled design are built for general propulsion efficiency, making it a versatile choice for recreational divers who want a boot-free, full-foot setup.
