There is fine sand inside the insoles when they are removed. I have done a full home cleaning, but I couldn't remove all the sand, so please judge from the photos. There are some minor stains, but they are still wearable. My boy liked wearing them a lot ^_^ They are a cool orange color. Shipping is planned via Yu-Packet Plus.
