Not comfortable for regular/narrow widths.  So I have this slide and the flip flop.  I bought the slide really to use at home.  I work from home, so I'm using them pretty much around the the house all the time.  I've had them now for about 6 months.  For starters, they don't come in half sizes, so I bought the next size up.  Although initially they fit, they start getting wider with wear and tear and I have medium feet - not wide, so my feet start feeling loose in the slide.  I've noticed in the last two months or so pain in the side of my right foot.  I've come to the conclusion that it's being cause by this slide- because my foot is not supported and my metatarsal is getting hammered by that.  I honestly think overall Oofos are over priced and over hyped.  The flip flops fit more comfortably, but I also haven't worn them as much as this one.  I would say if you have medium to narrow feet and wear half sizes (i wear a 6.5) SKIP these.
