Been looking for a pair of shearling boots for my 5 year old daughter and have had no luck until now. She has extremely narrow feet - we've tried every brand, Uggs, Stride Rite, etc. and if the length fits, her feet pop right out of them. When I opened the box, I was thrilled to find that the opening of the boot was not going to swallow up my daughter. They were the appropriate width for a little child's ankles/calves to fit snuggly yet comfortably in (there is plenty of room to tuck in pants). My daughter normally wears a size 12, and based on the feedback to go up a size or two, I got one size larger, 13 and they fit perfectly. If your child has very wide feet, you may want to consider going 2 sizes up? We will not be sending these back!
