The shoe seems to be a very simple, but well executed, design.  I bought a pair to use as slippers and I expect they will work fine in that role.  They are very narrow and while the upper does stretch to accommodate my foot the sole is a bit narrower.  Again, they will work for my purposes, and might work as an everyday shoe for someone with narrower feet, but it is safe to say this is a shoe that is probably not for everyone.
