Let your child enjoy summer without stuffy feet
Children can dive into fun with the Threo first walkers. The featherlight design makes them perfect for hours of play. The mesh lets cool air in, keeping toes dry and happy.
Gentle touch
Our water shoes are made of an incredibly soft material. It provides maximum comfort and prevents irritation on the skin after long wear.

Secure fit
The silicone soles ensure the shoes stay securely on, even during the most active play. No more worrying about lost shoes or your child slipping over.

Easy to wear
Velcro closure allows you to put the shoes on and take them off in a matter of seconds.

Size guide

To measure your child’s feet for shoes:
Make your child stand in bare feet with the heel against the wall.
Place a ruler on the floor parallel to your child’s foot with the end of the ruler against the wall.
Find the length from the wall to the end of the longest toe.
