Babies & Crawlers

0-18 MONTHS

Soft soles are highly recommended during the first 24 months of a baby’s life as they are very flexible and allow for more natural movement and much better balance. This type of shoe is great for those first months of transition between crawling and walking. Our soft-soled baby shoes (Yale baby shoe and Powell baby shoe) will help to strengthen and develop their little foot muscles and tendons for a faster and healthier learning experience.
