How often do you need to replace your sneakers?
I have read that they should be replaced twice a year. I wear new balance sneakers and shoes and when I take out the insole it is very thin and has no arch support, the arch support appears to be built into the shoe itself. So how often do I need to replace my sneakers and shoes? I am prone to joint problems so I don't want to wait to long, but don't want to replace them unnecessarily. I am still wearing the shoes and sneakers I got a year ago. I have a pair of shoes I wear outside and a pair of sneakers I wear inside. I am not a runner. My main concern is losing arch support as I have someone flat feet. The tread on the bottom of the shoe look fine. Should I replace them?
