Cressi Rocks adjustable kids’ snorkelling fins

The Cressi Rocks fins in lilac/white are a compact choice for children’s snorkelling. Soft rubber foot pockets, adjustable heel straps and vented composite blades give young snorkellers a straightforward pair of fins for family beach trips and holidays.

Supplied as one pair of fins. Choose the fin size from the available options; these fins are designed to be worn barefoot.

Features and benefits

Soft rubber foot pocket: provides a flexible contact surface around the foot for barefoot comfort.
Adjustable open heel: lets you set the strap tension within the selected size range as the child’s fit changes.
Release buckles and a wide pull loop: help with putting the fins on and taking them off.
Vented composite blade: combines a short, manageable blade with openings that help water move through it during a kick.
Two junior size ranges: let you choose according to foot length instead of relying on age alone.

Size guide and approximate ages

Please check the Cressi Rocks fin size chart and measure both feet before choosing. Use foot length as the main guide, then check the actual fit.

Fin size	Foot length	EU	UK	US	Approximate age
S/M	16–20 cm	26–32	8.5–12.5K	9.5–13.5K	About 3–5 years
L/XL	20–24 cm	32–38	13K–5Y	1–6Y	About 6–10 years

Age ranges are a guide only; individual fit varies. K and Y identify children’s and youth shoe-size numbering. A child’s age does not establish their foot length. Do not choose a loose fin just to leave growing room.

How to measure and check the fit

Have the child stand with their heel against a wall. Mark the longest toe and measure the distance from the wall in centimetres. Measure both feet and use the longer measurement. With the fin on a bare foot, adjust the strap so the fin feels secure without pinching or excessive pressure. Try the fit before entering the water; if the foot sits between size ranges, ask us for advice.

Choosing a complete pack

These fins are available in Cressi Baron Junior and Rocks snorkelling packs. Mask fit is separate from fin size, so check the child’s face shape and the mask guide as well as foot length.

Care and storage

Rinse the fins, buckles and straps in fresh water after each use. Dry in the shade, store the blades flat and keep them away from heat or heavy objects. Check the straps and buckles before a trip. Children need close adult supervision while snorkelling.
