I just received a size 10 for my not-quite-4 year old daughter. They are a little big but with socks they are fine. The Merrell Barefoot kids collection is the best of a small category - flexible/barefoot style shoes for little kids. My daughter loves these shoes, and can get them on and off herself. They seem typically durable. I am sad to see that size 10 (toddler) is the smallest size available, and that your infant sized shoes are all stiff with big heels. My one-year-olds are small for their age and are probably going to be five years old before they can wear these unless you start making them smaller. Please make lightweight, flexible shoes for the stage in between learning to walk and being able to run :) On another note, my husband, daughter and I all have Trail Gloves now. It's pretty cute.
