Fantastically made child's sandal. My daughter has long, narrow feet. It is difficult to find shoes that don't slip off her heel. The ankle strap is adjustable so we can be sure the shoe fits snugly and secures it to her foot so the heel strap doesn't rub and cause blisters. I can also attest to the quality of the shoe... We purchased this sandal in last year's design and they are still in such good shape that we're saving them for our youngest daughter.
