I purchased these moccassins for my 12 year old who wears a size 3 1/2 to 4 in girls shoes.  I had ordered the smallest size available, a Women's 5, and when they arrived they were too small.  No problem, we sent them back and ordered a size 7 in Women's and the shoes fit perfectly.  Had the hardest time finding moccassins for my daughter in the children's section but these are perfect and she loves how comfortable they are.
