I've only worn them for about a week, but, I don't foresee any complaints or issues coming up. They're hands down one of the comfiest shoe/boot ever, they function and grip like a dream. I use them on my bike and the airflow on my feet is awesome lol. 5 stars, make sure you order the right size though, I'm a 8.5 in keen and in other brands I'm 9 to 9.5.... that being said, every brand has a different size. I would order a half size down.
