These little boy squeaky sandals are eye catching and ultra cute!. Flexible, anti skid rubber soles help with traction and stability. The squeaker mechanism is incorporated into the heel and provides endless entertainment & fun for pre-walkers and accomplished walkers alike. The squeak also provides security for parents, as they act like an audible radar system to let you know where your little one is at all times. The rubber soles provide an excellent grip of the floor and aid your child's posture, balance & confidence whilst walking. The shoes have a Velcro strap to ensure a perfect and secure fit every time. Each pair comes supplied with no-squeak valves that are easy to exchange.
