I had ordered an 8 and an 8.5 in this shoe.  The 8 was very small in the toe so I thought I'd try the 8.5.  The 8.5 was still very narrow for my toes and slipped in the heel.

Too bad as I loved the shoe - it's really pretty and Asics usually fits me.  I have found that because I use toe spreaders and spread my toes while doing yoga, this is a common problem for me.  I need a wide toe box so it may not be that the shoe is narrow it may be my toes don't like being confined.
