    Hi, I bought a pair of Vaporflys in 2019/2020 (can’t remember when exactly). Since then I have worn them very sporadically. One half, one Marathon, a couple of 5ks. My understanding is that these type of shoes have a limited shelf life in terms of performance benefit, but I alway see it expressed in mileage (i.e over a certain mileage the performance benefit decreases). My question is, does anyone know if there is a time period over which the show’s performance benefit decreases independent of how much milage is done in the shoe (e.g. would a minimally worn 5 year old pair of Vaporflys retain their performance advantage or would their age count against them)? Thanks.

    Great question. I have my OG pair of Vapors as well. They sat idle for over two years during Covid and probably have ~150 miles on them. Occasionally take them out for a speed workout, but I can’t bring myself to throw them out. They still feel pretty good.

    Your question is easier than OP's. After 150 miles the magic "pop" has gone.

    I never run more than 2 marathons (and one longer training run each cycle) with one pair of Vaporfly's. So never more than 100 miles as my A pair.

    I don't throw them away however. Imho they make for great training shoes for easy runs and long runs. I bin them after 400 miles.

    I don't have any scientific studies or first hand knowledge, but a really smart engineer I discussed this topic with said that type of foam really should not noticeably degrade over time if stored in reasonable conditions (room temperature). It may be different if the shoes are exposed to heat, intense sunlight, or extreme cold for significant periods.

    150-200mi for me but for an “A” race where you want the most boost from the shoe, you probably want a pair with under 100mi on them

    It depends what you want out of them. If, for example, you are flying to Boston to race, the cost of a fresh pair is worth it. They are not that expensive compared to everything else people spend money on (for their hobbies). I would not race in an old pair.

    That said, I agree with the previous guy who keeps the older pairs for training shoes. They are still super, super light and have more pop than most shoes (even when they are old). I only throw them away when they feel like the heel is "caving in" a bit. I go by feel.

    The question was not if you should replace them after x miles, but if midsole foam degrades even if a shoe isn't used, and it doesn't.
