The TUSA Liberator SF0113 fins are open-heel dive fins with a flexible blade base, tip winglets and a 3D anatomical heel strap. Pair them with correctly fitted dive boots for scuba diving or snorkelling where you want foot protection before entering the water.
Features and benefits
- Soft material at the side-rib base: allows the blade to flex from close to the foot pocket.
- Blade-tip winglets: guide water flow at the end of the blade.
- 3D anatomical strap: follows the shape of the heel over a dive boot.
- Open-heel pocket: accommodates suitable boots, with the final fit checked as a complete boot-and-fin combination.

Liberator SF0113 size guide
| Product size | Manufacturer size | Foot length guide | EU shoe size guide |
|---|---|---|---|
| XS/S | S | 22–26 cm | 35–40.5 |
| M/L | ML | 26–30 cm | 40.5–46 |
These are the SF0113 manufacturer ranges. The numeric conversions in older product-option labels differ; select the XS/S or M/L letter size using this guide, then confirm the fit with your boots. If you are uncertain, ask our team before ordering. This is not the older SF5000 Liberator X-Ten.
These are open-heel fins for use with dive boots. Boot thickness, sole shape and foot width affect the fit, so try the fin with the actual boots you will wear. The heel strap should hold the boot securely without forcing your toes against the end of the pocket. Boots are sold separately with the standalone fins.
To measure your feet, place paper against a wall, stand with your heel gently against the wall and mark your longest toe. Measure from the wall to the mark in centimetres. Repeat for the other foot and use the longer measurement. Where a model has no foot-length chart, contact us with that measurement and your usual shoe size rather than using another fin model’s chart.
Care and storage
Rinse in fresh water after use and remove sand from the foot pockets and adjustments. Dry in the shade before storing away from heat and direct sunlight. Store blades flat without bending them or placing heavy items on top. Check straps and buckles before your next swim.
