Thanks to a zipper, all models are easy to slip on and have a soft rim. The shoes are roomy from the inside and have a warm sheep wool insole. As suggested by the name, the surface material of Baby felt shoes is genuine sheep wool felt. Wool felt has outstanding natural properties, it is breathable, resilient and naturally warm. Their shafts are a little higher than in the other Kuoma Baby shoe versions. This model has no separate lining.
