These are pretty cheap, but my 1 year old doesnt care.  The bottom is pretty thin, but that has actually been nice because a lot of his shoes are the soft soles and are flexible.  He struggles a little with his other sandals that have thicker bottoms with less flexibility.  I had to use a lighter to burn off a lot of fibers already, but I don't expect these to last beyond the summer and won't fit after that anyways.  I would buy these again as they were inexpensive and work fine.
