Unless you're not planning on walking anywhere, I would very weary of these.<br /><br />After trying them on and JUST walking around the house in them, I noticed stress marks near the heel on the sole (which is smooth, hard plastic). After less than 30 minutes, there were already signs of imminent catastrophic failure. If the heel splits from the body while you're walking, there's a good chance of injury.<br /><br />Also, they smelled funny.
