Haha this pic in post above is funny because person can still steal the slippers.However on the other hand my shoes and chappals have been stolen 1 or 2 times, but I have never seen slippers being stolen!
You don't need to tear it. The design of the chappals are such that there are 3 points plugged in. You will need to remove the left point on one and the right on the other, remove the lock, and push the thing back in. You will have a ready to use pair of chappals.
