Supporting joints

So Dragon Dancing is alot of fun, unfortunately it appears to be hard on knees, ankles and feet.  So although the sprained left toes are now fine (wearing shoes to play safe).  I find the sudden stops and sharp turns are tough on my knees.  Should I mention my age?  Nah other people younger than me have strains as well.  So I have been investigating support products for knees ... don't really like the brace as it really restricts the actual movement of the joint,  tensor bandages don't stay in place but ah hah! I found something called KT Tape.   Its a tape, so it stays in place, but with elasticity and wow what a difference.  Two strips on the outside of my knee provides support and you don't feel any restriction of movement.  Just be careful when removing it,  it will remove hair if not done correctly.
