Shoes

Hi mummies, I have just bought 2 pair of hard soled shoes for my 17 months old baby. He was wearing soft sole shoes since 1 year old. The sales lady told me that he should wear a hard sole shoe at his current age and it can help him for his tip toe walking. After googling, some experts said that soft sole will be better as their feet are growing. I need advice as I am a ftm. Thank you very much.
