After knee surgery a few years back and an MCL tear just a few months ago, I have chronic knee issues. I’ve been wearing nothing but shoes with these amazing insoles in them to help with my knee for the last few weeks straight. Today I grabbed a pair of shoes I wear less often and forgot to switch out the insole. I can feel my ankle breaking in hard, and my knee is pulling with every step for the first time in weeks from simply walking around. I knew these Arch Mobility insoles helped, but I am honestly shocked at the difference I feel not using them. Truly a must-have for anyone who spends time on their feet, knee issues or not. Feel the difference!!
