I dont remove the shoe trees frequently so they wont be used but maybe once a week. Cozy and comfortable without that annoying ridge on the back of the slipper. See included picture. The top fits great with a little extra room and the bottoms are pretty big. My toddler was so excited to wear these when they came in. Great in the rain. And on top of all that, it?s ADORABLE! I love the style of these shoes and their versatility. She?s a size 13/1 and I ordered the size 1girls. And the sizing is spot on!
