text: Initially I loved Haviana's and have purchased seven pairs over the past three summers, 4 flat pair and 3 wedge. With each pair the back holes that holds that straps in place loosen over time and with every pair I own, the strap eventually popped out of one of the back holes. The force that happens when you lift your foot while walking must cause the grip to loosen around the strap in the hole. I pushed the strap back in, but it is a temporary fix. Inevitably, the strap comes out again. Though I wore my Havianas almost daily in the summer in place of house slippers, I do not wear them year round and I have them on for only 3-4 hours a day. After only 2-3 months of wear, the strap came out of the hole in every pair I've owned. The comfort of Haviana's cannot be beat, but I do not plan to spend $30-35 for a pair of flip flops that last only a season, at best, or 2 months, at worse. I would love it if Havianas would fix the problem.
