that is a training companion to the rc elite, same foam no plate. The rc elite 1 is imo a fantastic shoe. Faster for me than the 4%, Next%, and Endorphin speed. Out of those shoes, the 4% flyknit is my 2nd favorite. It's very similar to the rc elite 1, with the geometry of the drop and the feel. If you miss that shoe I consider the rc elite 1 an improved version of it.
For me the next%s caused pain in my hips and quads, something about the lower drop I would guess. The rc elite 1 and 4% are both a 10mm drop.
There is a 2nd version of the rc elite coming out this month. It's slightly heavier but has more foam and a more aggressive plate, so it's said by shoe reviewers to be as fast as the first one with more cushion. Also has a roomier upper if you need that. Have not tried it myself.
