1. Wearing the Wrong Shoes
Your knees rely heavily on your feet for alignment. If your shoes are old, unsupportive, or completely flat (like flip-flops), your knees take the brunt of every step.
Wearing high heels or shoes with worn-out soles changes your center of gravity, increasing pressure on the inner part of the knee joint. This accelerates wear and tear on the cartilage. The Fix: Invest in shoes with good arch support and cushioning, specifically designed for walking.
