I bought these flip flops for Mallary last year and I think they may have lasted a month or two... I finally got around to fixing them.
Before: The toe holder thing ripped out.
After: I used some of my sparkly black ribbon and now she has fancy new flip flops!
DIY: I simply cut out the original plastic straps to the flip flops, knotted the ribbon underneath after making sure it would fit Mallary's feet okay. After knotting, I filled the rest of the holes with hot glue.
Who knows? They could last longer than when I bought them from the store...
