PLEASE CONSIDER!
Kids grow too fast and these slippers lasts quite a long time. They should have about 1/2 an inch growing room in the toe box. The opening of the collar is purposely made smaller so even if the slipper is slightly big it will stay on, and as the sheepskin mats down the collar will form to a perfect fit.
I have been selling my craft at the well-established Arts & Craft Shows throughout the western states since 1984 and my suggestion comes from over 34 years of experience & happy customer’s feedback.
