Just bought these in person today - I have a few pairs of Birkenstocks & Birkis, but only one with a soft footbed before today! Will be great for extended sightseeing, etc., and I wanted a pair with the ankle/back-strap for the odd times I really want the sandal to be secure on my foot (like roller-coasters or something). I have a high arch, and the arch strap is a bit tight on its loosest setting - any snugger & I would have had to keep myself from buying them (I tried another style with a thin arch strap closer to the ankle once, and could not buy them). Taupe colour is good for wearing with anything! They fit me the same as my classic two-strap and my clogs...which is the tiniest bit smaller than my Madrids (one-strap style, which reviews as fitting a big big). I usually wear a 9 in shoes, and often an 8 in sandals, so I get 38 in Birkenstocks. 38.5 would likely be my perfect size, if they came in half sizes! 39 looks just a bit too long for me, but likely ok on a similar foot if you don't mind a bit of extra space.
