Just can't go wrong with Birkenstock!  A little pricey for a strappy sandal but you get what you pay for.  I have kind of narrow feet & Birks have always fit well. These are even better with the straps that can be tightened around the ankles.  The tightest option keeps them from flopping around while I walk.  I purchased Size:39 M EU / 8-8.5 2A(N) US | Color: Mocha Birkibuc - Size fits my 8-8.5 foot perfectly. Love the color too!  Glad I splurged :)
