Only took about 20 minutes to put together. I feel little snug. Earlier i used to spend at least 1 hour for packing and 30 min for unpacking. Seller shipped fast and even sent a personal note! I bought these for my 90 yr old mother. These are good quality winter boots, perfect for toddlers! The only reason I gave them 4 Stars is because the soles collect an immense amount of food scraps, and are unbelievably hard to clean. Im beyond the 30 day return window; but, Im hoping someone will see this review and reach out to me for a return/replacement. They are soo colorful and pretty large . The top is attached to the bottom section by a little hinge so it wont get lost and so it can create a seal.
