The Vivobarefoot Ultra II Kids in Flintstone is a barefoot, amphibious shoe made for little explorers who never stop moving. Super flexible, ultra-lightweight and quick-drying, it’s perfect for running through sand, splashing in rivers, rock‑pooling and everyday summer play.
Key Features
- Amphibious design: Drainage holes and open structure make these ideal for water play, beach days and wet playgrounds.
- Barefoot feel: Thin, flexible sole lets kids’ feet move naturally and feel the ground for better balance and coordination.
- Super lightweight: Minimal construction keeps them easy to pack and comfortable to wear all day.
- Quick-drying materials: Synthetic upper and open design allow water to escape and the shoe to dry fast.
- Secure fit for active kids: Enclosed design stays on much better than flip flops or loose sandals.
