I think the Vaporflys are still the fastest out there but I'm on my second pair and they still feel wierd mostly due to the bounce but they are narrow in the midfoot and the height does make them a little unstable cornering and if you pronate/suplinate the height, lack of stability and how they accelerate your roll through will exacerbate any wonk you've got going on. They are undoubtedly faster than anything else at all speeds if you have narrow highish arches and decent form which i probably a lot less people than are running in them probably doing themselves more harm than good wearing them they're everywhere now and i've even seen guys wearing them in the weights room which is just stupid. They are coming up heavily discounted in older colourways everywhere online so not even much more expensive than a decent mileage shoe. I've got endorphin speeds and on my second pair of pros and i wear them both a lot they suit more foot shapes and feel much more natural like a normal trainer but faster. My long runs are rarely much longer than 20 k now so use the speeds and use the pros for faster stuff. The pros are a little quicker than the speeds but harder on your feet. I'm used to carbon plates now but if i run in the pros even 3-4 times a week i have to roll my feet out on the hard ball as they start to ache. Based on that i think endorphin speed as an introduction to this new shoe tech and taking it from there would be a sensible approach.
