The upper is made of a large area of mesh fabric, which ensures air circulation inside the shoe, allowing heat and moisture to be dissipated in a timely manner. This helps keep the baby's feet dry and comfortable for extended periods, avoiding discomfort caused by stuffiness and dampness. The toe cap is noticeably thickened and reinforced, creating a sturdy protective zone that effectively cushions against frontal impacts during walking, safeguarding the tender toes. The wide U-shaped collar is elastic, making it not only easy to put on but also gently wrapping around the ankles to prevent chafing.
