I bought these for my 2 year old. He is size 6 and the smallest boot I could find was an 11, but these work well for him. These are easy on, easy off, but actually can snug up quite a bit due to the velcro. I've ridden Burton boots for 15 years and keep going back to them because of the quality. I am stoked I was able to find that same quality for my son in a kid's-sized package.
