Reima Lean J Children's Water Shoes – Blooming Lilac (5400091A-5451)
The Reima Lean J in "Blooming Lilac" is a lightweight, high-performance water shoe specifically designed for summer adventures. Whether at the beach, pool, or lake, these shoes provide essential protection with a barefoot-friendly design. The vibrant purple colorway (Blooming Lilac) is stylish and easy to spot, while the technical construction ensures feet stay safe from hot sand, sharp stones, and UV rays.
Key Technical Features & Benefits
- High UV Protection (UPF 50+): The textile upper is designed to block 98% of harmful UV rays, protecting the sensitive skin on the top of the foot while swimming or playing in the sun.
- Barefoot Design: Features a Zero-Drop sole (completely flat) and maximum flexibility. This encourages a natural stance and allows the child’s foot to move freely, supporting healthy muscle development.
- Ultra-Lightweight: Weighing only approximately 62 grams, these shoes are among the lightest in their category, reducing leg fatigue during long days of play.
- Quick-Drying & Breathable: Made from a synthetic blend (Polyester, Cotton, Elastane, PU) that does not absorb water and dries rapidly, preventing discomfort once out of the water.
- Happy Fit Removable Insole: Signature Reima insoles with a printed guide to help parents easily verify if the shoe size is correct and ensure a perfect fit.
- Vegan & Safe: Fully vegan construction and free from harmful fluorocarbons (PFC/PFAS).
Practical Maintenance
- Machine Washable: These shoes can be washed in a delicate cycle at 30°C. It is recommended to use a washing bag and remove the insoles before washing.
- Easy Slip-On: The elasticated opening and heel pull-loop allow children to manage the shoes independently, fostering autonomy in the locker room or at the beach.
- Safety Note: While the thermoplastic rubber sole provides a great grip on natural terrain, caution is advised on wet, tiled surfaces (like indoor pool decks) as they can still be slippery.
Sizing & Fit Guide
Reima sizing already includes a growth allowance. For water activities, a snug fit is preferred to prevent the shoe from sliding off while swimming.
