Everything about these kicks is cool; from the "techie" looking soles to the laid back vibe of the canvas uppers the Cushe M's are sweet. Do not be confused by the term "slipper". Slipper ...in this case *not* referring to something pink and fuzzy but more a description of how you get them on and off; they slip on, they slip off. Consider these Cushes high-tech moccasins. They are light as a feather. They are very comfortable. They are minimalist in design. They are very ...cushy. Wear them with socks ...wear them barefoot. But get them sized right. If you're a half-sizer go down. Yeah it might feel a little smaller than you're used to but the M's have a wide toe box and the canvas will stretch. It might be you have to size them for socks and take a looser fit when you wear them au naturel. Or size them so your dogs can run naked and do a thin sock. I'd go with the naked dogs. The soles provide sticky traction on rough surfaces but not so much on smooth hard stuff. And very much like a good pair of moccasins, these "slippers" conform to your feet the more you wear them. First time you put them on they'll feel a little weird ...it's the soles on them ...but give 'em a chance and wear 'em a bit and they'll get Cushe comfy real quick.

Update: That comment I made about traction on smooth surfaces? Forget it. After wearing them for a bit the soles roughen up a bit and they are great on any surface.
