The Cressi Free Frog fins use a full-foot pocket and a flexible, non-vented polypropylene blade for snorkelling and recreational diving. The blade extends from above the pocket, giving this model a longer overall profile than short travel fins.
Features and benefits
- Low-modulus polypropylene blade: combines flexibility with a non-vented blade layout.
- Full-foot pocket: designed for bare feet, or thin fin socks where the fit allows.
- Above-pocket blade attachment: extends the working blade surface along the foot pocket.
- Heel pull tab: gives you a grip point when putting the fins on.

Open the Cressi Free Frog manufacturer size and dimension chart
Size charts are a guide only; individual fit varies with foot shape. Check both feet and try the fins with any socks you intend to use. The pocket should hold the foot securely without curled toes, pinching or excessive movement. If you are between sizes, ask our Hallam team for fitting help.
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.
