Sadly, I returned these sandals.  I used to LOVE See Kai Run, which is pretty much the only brand that my son has worn since he started to walk...He is 4 years old now.  I must say that I am disappointed with the quality of their shoes.  Definitely not the same as it used to be.  Not sure if they need to cut costs to be profitable, in the long run, they will lose customers...So sad, really thought I had found a brand that would uphold its integrity and standards.
