ReactX Rejuven8 Slip-On (Men)

These slip-ons are just OK for what they are; the ReactX sole mainly provides support for the heels, so if you're using these to combat plantar fasciitis these might be suitable. Otherwise ReactX soles are probably best for trail running shoes (e.g. Wildhorse 10) that allow you to "feel" the terrain better. I'd really like to see Nike use their ZoomX (cushiony) soles for slip-ons but so far that hasn't been the case. I wear a size 10 in Nikes (but a size 9.5 in pretty much everything else), and the size 10 in these shoes fit as expected. Outside of the sole, the design suffers a bit from breathability issues. Despite the Swiss cheese holes along the top, they still feel confining due to the material, which produces a "convection" effect as a result. There's a reason these shoes are going on sale on multiple sites, so either take advantage if these somehow meet your needs or wait for improvements (hopefully to the insole) in the next release.
