However only few weeks into use AROUND HOME the soles started splitting. Removal, trimming, and re-installation took a total of about 30 minutes. I would caution that you should have your little one wear these only for a couple of hours before wearing them all day to break them in and get used to them. No las volveré a comprar y no las recomiendo lastima. large. This is a great shoe! - Most comfortable in the group. Good show gone bad. Very comfortable and the sound is amazing. This actually makes the transparency mode slightly worse so if that matters to you don?t use these.
