Isn't that a stupid headline?  Ok,  they can't cripple you.  But they can severely injure you.  I'm not kidding!!! Get this.  As if we don't have enough to worry about, according to a Discovery Channel medical expert:

Flip-flops can cause "serious injuries to feet, ankles, knees, hips and even our back," warns Discovery Channel medical expert Dr. John Whyte. "Over time these injuries can lead to serious bone, tendon, and joint damage..."

Really?  REALLY?  Maybe if you wear them day, nite, in the snow, rain, spring, fall and summer they may damage you. And I will admit this-I've been injured many times by that annoying  little post that goes between your big toe and the next one over (your index toe?) .  That thing KILLS!   And I do get pain in my joints alot .  But COME ON! If I went to a doctor tomorrow, I guarantee you that he's not going to say to me "did you ever wear flip flops when you were 4 years old, perchance?"   There ya go!!"

Once again, they're going overboard, don'tcha think?  Yea, you can die from sweet and lo too if you eat a bucket of it every day with a big spoon.  But I'll go out on a limb here (no pun intended) and tell you if you flip-flop it in moderation, you're probably safe

How can you tell if you have a good pair of flip flops?  You can read the recommendations here from the Huffington Post.

(actually, that annoying "flip flop" sound that they make is bad for your MENTAL health, I can tell you that!)
