I've heard that the current Metal powerlifting shoes are not as good quality as the originals? Is this true? I'm looking to buy a new shoe with a flat heel. What would you guys say is the best option? I'm thinking of either getting the Sabo deadlifting shoe, the Sabo good lift shoe, the Metal powerlifting shoe, or the Rebok crossfit lite RT. I've heard some people say the old Metal shoes are the best but not to wast money on the new ones since the quality went way down. Does anyone agree with this?
