These shoes are perfect for baby's first steps, indeed anti-slip sole allows the child to move without slipping while aillant contact with the ground thanks to the flexibility of the sole. Bungee allows the liner stays in place with 4 legs or 2 feet without compressing the ankle. More resistant the leather looks. I find it more fun to have a wide choice of colors and designs, it really allows you to choose the pair heart stroke. To my son of 15 months, this is the perfect product ... and mom I am is filled! Good value for money.
