I've been buying a new pair of Chacos from my local outdoor store once a year for the past 4 years. I wear them almost every day and treat them very hard, so I like to buy a new pair once a year. This was the first time we've ordered them online (so we could easily get a size up) and either they're made differently or I got a bad batch. The left one squeaks with every step (I've had them for a few weeks now and it's still happening) and the straps on both need adjusting every time I put them on. They won't stay where they are. However, they are attractive and comfortable, fit well and appear to be perfectly durable.
