The highly-regarded Vaporfly 2, known for its balance of sharp performance and stability. Vaporfly 3 became more mass-market oriented, and while Vaporfly 4 got closer to the 2, I still feel like the 2 allows for faster running. I love them and have bought four pairs, with two worn out and this one, which I used with care. According to my Garmin records, I've run 190km in them, and I think they can still be used in races. Of course, they're also good for training to get used to the Vaporfly 4. What do you think? After scrubbing them with a brush, I had them cleaned. There are still traces of fine dirt, but they are at least clean. Thank you for looking.
