I have had worsening painless knee popping in the last couple of months. am i wearing the wrong shoe or should i get it checked out?

You should check it: Painless pop in the knee have many reason, one the common cause condition call pilca, the orthopedic surgeon could check it for you.

Knee popping matters: Worsening painless knee popping is worth checking... It's like realigning your car's headlights. Plica syndrome (correct spelling) is a fold of lining membrane getting pinched. Patellofemoral tracking syndrome, pes anseronis syndrome, it band tightness, and lower leg twisting or fibular displacement are different malalignment conditions.
