Wonder if he used that shoe when he hit OTQ with a 1:04:00 half. He also ran that pace at RnR AZ
for his RnR Arizona half marathon he used the Hoka Carbon Rocket (carbon plate, but not much cushion), as seen in pictures.
For most of his tempo work he was using this shoes (as Fauble do also). Now apparently they both test the new Hoka race model.
This new Hoka model (there is a specific thread about that) can be seen in video from Scott Fauble and the photo on Jim Strava from Pemberton 50k few day ago. Apparently it is an evolution of the carbon rocket.... as per Ben Rosario.
