Depending on usage, a pair of Crocs should last between three and five years. For those who are donning a pair of Crocs for work every day, they may only last a couple of years, especially for servers or those moving around frequently on the job. Broken straps or pieces cannot be replaced, so if a pair is damaged it’s time to buy again. Brightly colored options may also start to fade over time, but that doesn’t mean their comfort or support is compromised.
