Received my pair today. Love them already. With this pair I went TTS but I would recommend going up .5, even though I feel this is doable. Will try .5 bigger on the red pair which I am going after next. Here is pic with and without flash.
Most if not all of the full price Nike storeswill get them but don't expect a LG4 in terms of comfort since they are a racing flat and will wear out much faster and will not have nearly as much cushion. Personally i would just wear them casually unless you are an insane runner.
