When babies are just starting to walk, the goal is to let their toes splay naturally, similar to being barefoot. 'Sock shoes' or lightweight, flexible-soled shoes are excellent choices for this stage. As they become more active, you can transition to flexible, barefoot-style shoes like Aretto or Nike Sunray Protect sandals. Avoid shoes with stiff soles, and prioritize comfort and flexibility over aesthetic designs to support natural foot development.
