Birks are one of the most comfortable shoes on the market, and this style is no different.  It has a bit of a nicer look than the more traditional styles.  It is feminine and looks great with jeans or a sun dress.  The trap between the toes is very comfortable.  I cannot wear the Gizeh style of Birks because the plastic between my toes gives me really bad blisters after even just a short time.  I can wear these all day and have no discomfort.

I have read a lot of suggestions about the sizing of Birks.  IMO they fit true to size.  The 1st pair I sized down because of suggestions from others, but I will never make that mistake again.  These shoes are designed to have a bit of clearance in the toe and heal, so if your toes or heal are right at the edge they are likely too small.  I usually wear a a 9 1/2 and 40's are perfect for me.  My feet have a bit of clearance at the toe and heal and I can bend and move in these.  My feet have freedom, but they also have great arch support.
