Going to have to find a way off concrete. in General Chat Posted July 24 https://www.footlevelers.com/ I’ve been using these for 4-5 years, and just got 2 new pairs of insoles 2 months ago. The last 2 pair made it the 4-5 years I’ve had them! I put my work boots/shoes on a boot dryer every night to help them stay dry, and that prolongs the life of them. I’ve had f’ed up feet my whole life, and after some back issues my chiropractor got me into these foot levelers. I definitely think they help me!
