The Puffer Bootie Baby is designed to keep little feet warm, toasty, and safe. Lightweight and insulated with 3M™ Thinsulate™ 150G, and cold-resistant down to -20ºC (-4ºF), they provide exceptional warmth without being bulky. The water-repellent nylon upper keeps moisture out, while the soft fleece lining keeps feet dry and comfortable. Featuring two elastic drawstrings at the ankle and across the top, these booties are designed to stay securely in place when worn over socks or shoes. The flexible, non-slip PU sole provides good stability for first steps or stroller rides. Perfect for quick outings or all-day wear, these puffy booties make it easy to head out quickly and stress-free.
