Mares Nateeva Junior adjustable snorkelling fins
The Mares Nateeva Junior fins combine a soft foot pocket with a lightweight, responsive blade for family snorkelling trips. Their adjustable open-heel design and buckle-free strap make it straightforward to set the fit, while the clip-together feature keeps the pair together for transport.
This listing is for one pair of junior fins in XS, EU 30–34. Select an available colour in the options.
Features and benefits
- Adjustable, buckle-free heel strap: offers adjustment positions to help secure the fin within its size range.
- Soft, anatomical foot pocket: supports the foot while the open heel allows strap adjustment.
- Two-material blade: combines a responsive blade with flexible sections for an accessible snorkelling kick.
- Overmoulded rubber side rails: help the blade flex and return during the kick.

Nateeva Junior fin size guide
Choose fins by foot size and fit, independently of the mask. The XS junior fin is a different model from adult Nateeva fins.
| Fin size | EU | UK junior | US junior |
|---|---|---|---|
| XS | 30–34 | 11.5–2 | 12.5–3 |
This is a guide only; individual fit varies. Junior UK and US ranges cross from children’s into youth numbering. Use the EU range as the main reference and check the actual fit before use. No foot-length range in centimetres is specified in this chart.
How to check the fit
Measure both feet while standing, with the heel against a wall and a mark at the longest toe. Use the longer foot when asking for sizing advice. The foot pocket should feel secure without pinching, and the heel strap should hold the foot comfortably. If using Lycra or 3 mm neoprene fin socks to reduce rubbing, allow for their thickness and try the fins with those socks.

Build a junior snorkelling set
Pair these fins with the Mares Pirate Junior mask and snorkel set, or choose the Nateeva Junior complete snorkelling pack. Check the mask seal separately from fin sizing; children with the same shoe size can have different face shapes.
These fins are for recreational snorkelling. Practise the fit and kicking action in shallow water, with close adult supervision for children.
Care and storage
Rinse in fresh water after use, including the strap adjustment points, then dry in the shade. Store the blades flat and clear of heavy objects. Inspect the straps and foot pockets before each trip and avoid leaving the fins in a hot car.
