I have been wearing these shoes for a while now (almost 1 year daily) and I really really like them They are quite comfortable. Also great for style. I have also been wearing them non stop for a while because they are just so good of a sho (about 76 hours now I think) yes also sleep and that works just fine. And I'm still wearing them even right now. You can wear them at any time at any moment for any time just a great shoe the Nike air force one.
