My son loved these sandals! They light up not only when your kid runs but also have a switch-on button to light them up while sitting. They have each three Velcro openers which makes it super easy to put on and off. They are from the GEOX Respira line and are breathable at the soles. The sandals are in a very good used condition. ⭐️Size: EU 27, US 10 👟Material: Upper: 20% polyamide, 80% polyvinyl chloride Upper lining: 100% polyamide Insole: 100% polyvinyl chloride Outsole: 100% polyvinyl chloride ⭐️Special effects: Light up when in motion; have a switch on button - working (see video) 👟Line: Nintendo Supermario
