* {{H:cushioning}}. The Zoom Fly is heavier and less cushioned than the Vaporfly. It's not a bad cushioning-to-weight ratio, but after the Vaporfly it seems heavy and dead. The Vaporfly has an amazing level of bounce, where the Zoom Fly is pretty much like any other running shoe.
* {{H:drop}}. The Zoom Fly has less unloaded drop than the Vaporfly, but when worn they are both about 8mm. However, I found the drop on the Zoom Fly to be troubling, as I would expect on an 8mm drop, where I've got on fine with the Vaporfly. The Zoom Fly feels like it's 8mm drop, where I find something about the Vaporfly feels rather less.
* {{H:structure}}. While the Zoom Fly has a black line down the side, it doesn't have the carbon fiber plate of its better siblings. There is a plate, but it's simply plastic that "carbon infused" (whatever that means). The plate is a similar shape to the Vaporfly, though you can't see the seam on the side where the plate goes like you can on the Vaporfly. (The black line is nothing to do with the line of the plate on either shoe). In fact, I didn't realize there was a plate until it was pointed out to me and I probed with a needle to determine its shape. Unlike the Vaporfly, the plate in the Zoom Fly doesn't seem to cause any instability in either the front or the rear of the shoe. There's no noticeable structure of interference with your biomechanics, and there's not the instability that I find so troubling in the Vaporflywhich is nice. * {{H:flexibility}}. Even without the Vaporfly's carbon fiber The plastic plate, seems to give the Zoom Fly has similar levels of flexibility. Without /stiffness to the Vaporfly's carbon fiberplate, but without the Zoom Fly doesn't have the spring of the Vaporflyspringiness. It might still improve running economy, but the expected level of improvement would be hard to detect without a laboratory.
* {{H:outsole}}. You can see the hard rubber outsole as the black areas on the sole of the Zoom Fly. Superficially, this looks very similar to the Vaporfly, but on close inspection the pattern is rather different. I'm not sure if the rubber outsole is the same material on the Zoom Fly as it appears to be harder than the Vaporfly.
* {{H:shape}}. The Zoom Fly shape doesn't match the human foot, so the toe box compresses the toes. It matches the shape of the Vaporfly, and I found the Vaporfly gave me toe blisters until I [[Shoe Dissection| cut open the toe box]]. {{H:TryCuttingShoes}}.
