Snug Fit: Unlike other super thick non-slip baby socks, these non-slip grip socks are of moderate thickness and can easily be worn in small shoes. Wear the right crewneck suit for multiple occasions to keep your calves warm throughout the day. 4. Fit degree: medium thickness and high quality combed cotton. This makes them very breathable and stretchy, and easy to slip into shoes. They're also easy to slip on and off, so it's easy to get dressed. 5. Comfortable and stretchy: The design is gentle and not too tight, allowing the feet to move freely while providing a firm fit. This feature ensures that your baby will not experience any discomfort while playing, crawling or walking. Elastic straps around the ankles help prevent socks or boots from slipping off and ensure your feet stay warm and comfortable.
