I was very happy with these boots! They look clunky but my 2.5 yr old daughter did great in them. For the most part was able to pull them on herself. Once she pulled them on I’d help her stand and push her foot down in. She walked and trekked in the snow just fine too! They are fully lined and waterproof. Her feet were always warm and dry. Snug around the leg so no snow got in the top. Size is snug because they are lined. I like a snug boot so they don’t come off in the snow! I have the inserts also so I feel like these would fit a size 8-8.5. However, if your child has a chunky foot these may not work for you. Feel free to ask questions.
