I am shopping for LO's fall/ winter wardrobe and I am confused about what shoes I should be purchasing for him. He is currently 10.5 months old and just started really walking this past weekend. He is big so he is already close to needing a size 5 which means he is being bumped up to the less than flexible soles in a lot of shoe lines. I know it is important for him to be able to move his feet, especially when first learning to walk but am unsure of how long this remains important. I also am unsure of using the more flexible soled shoes in our climate which is extremely cold, wet and snowy this time of year. Any suggestions? Should he have an outdoor pair and an indoor pair or are the softer soled shoes ok for outside? What is warm enough? What brands do you recommend?
