I’ve used it several times, so has my husband, he is still using his original Chakos from 15 years ago and he wears them hiking and fishing, almost every day except when he goes to the office when it’s warm out. He’s had his original ones resolved twice, I’ve had straps replaced and soles redone for a couple of my pairs. https://www.chacos.com/US/en/sandal-repairs/ Gently used, minor damage to webbing at the rear of right sandal (see pic), these made it through two kids and still look great, they grow to fast!
