I bought these for my teenage daughter. All other children in LED shoes have LED clichés in the soles. These fiber optic lights look great both on and off. But when they're on, they steal the show! She loves them and says they are very comfortable. Be careful with the charging port on your shoes and they will last a long time. They weigh almost nothing! The outsole is durable and the highlight options can be adjusted to suit her fashion choice!
