Skechers is on a roll. I managed to get a pair of the Skechers Speed Elite Hyper in the zebra prototype color and they are pretty great. If you like the Razor 3, but want a shoe that is snappier for racing, this is the one. It's very similar, but with a lighter upper and a carbon fiber plate. The plate seems to be thicker in the midfoot/forefoot than the Vaporfly or Zoom Fly. Plenty of cushion and very light. Not as narrow and unstable as the Vaporfly in the midfoot. I am excited to see what the Ride 8 and Max Road 4 with hyper burst will be like. The Gorun 7 Hyper was a bit of a misstep. It has a nice midsole, but the upper is too voluminous in normal size and too narrow in the forefoot for a half size down.
