Review on Toddler Slippers Unicorn Cartoon Numeric_9 by Patrick Locke

I received these on December 25th for my 18 month old daughter and am writing this on December 29th. In just a few days, one of the slippers has completely lost its elasticity, see photo, so it does not stick to the foot. I bought these large ones because my daughter loves wearing my slippers and I thought she could grow up in them but the elasticity at least held them around her ankle but now they just fall off. and I don't see a way to fix it. disappointing.
