I have to agree with Sunshine (one-star review) about the discomfort and rubbing that this sandal does to the feet.  The leather is thick and stiff, and it hits right on a very sensitive spot on my feet where I had surgery.  Admittedly, I have very narrow, very flexible feet, but normally a Birk 39N fits me perfectly (8.5 to 9.0 in US)and is super comfortable from the first try-on.  Also, since some reviewers have mentioned that the shoe was flattering, I have to tell you that it wasn't flattering on my feet at all, much less so than all of my other Birks (I have a lot in various styles).  It made my feet look very wide and ugly.

I do think that if you could tolerate a break-in period, the leather would loosen up and come to fit your feet better.  And I'm sure it does look good on some feet.  (That's why I gave two stars, plus the fact that they were a fabulous buy.) But there was no way I could wear them long enough to break them in.  They just hurt too much.

Also, in case you're looking for Soft Footbed in the Larisa, I don't think it's available.  I couldn't find any.  I did find the Narrow, but I had to look a while.
