I recall using these socks only once or twice for short periods when my child was still a baby and not yet walking. Since they were not used for walking, the soles are in new condition. After that, they were stored indoors in a bag. The inner fur is still fluffy, and they are in near-new condition. The color is very cute, and I would appreciate it if someone who can use them would consider them. Size: 6-12 months. This was the only size indication. Measuring the rubber part of the sole, it is 14cm, so I estimate the inner sole to be approximately 11-12cm. Please note that these are amateur measurements.
