From reading reports the Streak doesn’t have the same cushioning as the Vaporfly and I wouldn’t be doing an Ironman in a set like I would consider the Vaporfly. I still want a pair to satisfy my curiosity but hate the fact what Nike is doing giving limited supply to jack the price. I generally run in Hoka so hoping they release a reported carbon plate version soon as I am sure it will be readily available.
I generally run in Hoka’s as well, but have a pair of Vaporflys I am doing one long a week in and a pair of Vaporfly’s I am only racing in. I do plan to run IM in them in 7 weeks, with possibly putting a old pair of hoka’s in my special needs at mile 13 if I really needed them for some reason. I can only give you my thoughts on the shoe which could be skewed with how the marketing is playing with my head.
