After about 2 months of wear only two lights are working on one of the shoes.  Only one front toe light and one light on the Velcro light up strap are still working.  The shoes themselves still look like new and will probably hold up for a long time.  They still look nice...until someone notices he's wearing light up shoes that don't light up right...  It was very disappointing to see my 4 year old go from showing off his cool lights to trying to hide the fact that one of them no longer works....  For nearly $40 these shoes really let me and my son down.
