Bical is a Brazilian shoe company that makes rubber-soled socks that are perfect for in-house wear, especially for those in the learning-to-walk set. The cushioned soles aren't the least bit slippery, which is a big bonus for any little one not yet steady on his feet, and actually stay ON little feet, which is an even bigger bonus for moms tired of backtracking in the stroller in search of shoes and socks that have made their way curbside. Best of all, they double as water socks - they're water-resistant and won't stretch when wet. Available in Brooklyn at Ola Baby on Court Street, or online at Kinga Shoes.
