They recommend changing your insoles every year, they break down. I can tell a huge difference between my old orange insoles and my new ones.Thanks! Superfeet have treated me well. I got the blue insoles after having really bad plantar fasciitis from running. Now I transfer the insoles into every new pair of running shoes I get and haven't had an issue. They've lasted me 10 years and I've been thinking about getting another pair.
