It?s very large in diameter so that it doesn?t touch the big toe except during movement. I like this because we were able to mount them slightly apart to allow more room for the kids to maneuver their bikes. and now the left earbud refuses to play audio anymore. Crocs are a great shoe for young children. I have no idea what Ill do once I graduate to 15 lb. I love having my spices close to our stove! They are comfortable and are a bit dressy without being too over the top. The battery life is as good as advertised and Ive had not issues running out of battery while using them thus far. Worth noting, I found mine on sale for $29 (not the more common $60-99). Muy buen material, trae una especie de cojín en la parte de la "correa" de la sandalia y esto lo hace muy comoda.
