A sturdy, comfortable pair of water shoes can last anywhere from 1-5 years. The sturdier and better-built the shoe is, the longer its lifespan. And, of course, cheaper “budget” shoes will typically break faster. Your activity will also affect its longevity. If you only use it for kayaking, a good pair of shoes can last up to 10 years. However, if you take them hiking, play sports, or run in them, they may break, forcing you to replace them sooner.
