Depends on how fat you are and if you're gaining or losing weight. There's some fairly recent research showing more muscle sparing on really low bf% individuals who are still at a deficit when consuming more than 1g/lb. If you're obese, obviously 1g/lb isn't necessary.
One guy at my gym has the new white Adidas... there's something plastic-y and cheap looking about them.
There are also two guys with the old white Adidas from like 2008 with the wood heels. Looks much nicer. Whenever they post videos online, there's always some clown offering like $300 for them
