That really depends on how often you wear them and what type of activities you do while wearing them. For example, if you only wear your insoles when you go for a walk or run, they’ll last much longer than if you wear them all day, every day. In general, though, most people find that their insoles last between 6 and 12 months. Of course, there are always exceptions to the rule. If you have particularly sweaty feet or if you often walk or run on rough terrain, your insoles may wear out more quickly. And if you take good care of your insoles (by cleaning them regularly, for example), they may last even longer. So if you’re wondering how long do insoles last, the answer is: it varies. But with proper care, your insoles should give you plenty of support and comfort for many months to come.
