I ordered these sandals in 2 sizes. I don?t normally write reviews, but I was compelled to comment because the customer service contact I received even though I don?t have any problems was unlike any order I?ve made on Amazon. I wear a womens 8 so I bought my chacos in an 8 and they are a perfect fit! Honestly I think Id rather have Boses offering (or Sonys, but they had weird-sounding excessive bass to me). Conclusion: I recommend these for running and sweating hard. This makes replaying through it again just not appetizing. Havent had them long enough to talk longevity but so far so good. Definitely plan on buying the next size up as she grows. I can tell that it will hold up and age well. By the end of summer, with moderate wear, the bows did fall off.
