I have no doubt there is some benefit but I'm amused by the idea of "wear is half as much, it lasts twice as long!!!"![]()

it does sound like exactly the sort of thing the shoe industry would like to spread around: buy more shoes and they'll last longer etc..
I'm not sure why letting a shoe "rest" for say 36 hours rather than 12 hours before wearing it again would necessarily increase its lifespan (if measured in terms of the total hours you actually wear the shoe)
