I got 2 pairs of these sandals (black and blue) for my dad and brother. After two weeks of wearing (blue sandals) the inside sole started separating from the edges and shrinking. It took the black sandals about a month and a half for the same to happen. Any direct sun or water will cause this to happen. I personally had a woman's pair or Riders sandals for pver a year, half the price,with no issues. The price is too expensive for this to be happening.
