I have been looking for a sandal like this for a while now, based on some photos on the Shon Modern website (they couldn't tell me who made those shoes).  These are not exactly the same, but close enough, and shipped quickly at a good price (as opposed to Trippen and others in that price range that Shon Modern sells).  Comfortable although the rocker takes a little getting used to.  The only reason I take off a star is for color:  black is practical but it would be nice to see a grey or other pale neutral, and because the sizing is a little funny.  I pretty much take a 38 in all Euro shoes, a 7.5 in US sizing, and a 5 in Doc Martens (which is the only UK-sized brand I'm familiar with).  In these, I ordered both the 7 and the 7.5 to see which fit.  The 7 is marked as a 38, and also a 5.5 UK, and it is just a little too big.  I've just ordered the 6.5 and will A/B them to see which one's going back, but in any case the 7.5 would have been enormous.  The box is marked 38.5, which I have never seen before, and also marked UK6, which I know is too big for me.

They are very comfortable on the footbed and make me realize I need a pedicure!
