We Geox chosen to do the feet of a good thing. Glitter and Blinkies had the concession to our daughter (5 years). In the first order of the left shoe has not shone in the replacement order of the right shoe has not lit up - we kept the two functioning and defective returned. So far so good. The shoe was worn daily for 3 weeks, followed by the hacking had expired on both sides. In a shoe 50 must not happen like that. We got then returned and paid for the shoes. For me the reputation of Geox has suffered under, as soon I'm going to buy any more.
