I never used to have a problem with Ryka, but now I seem to have difficulty finding the right size.  I'm keeping these, but they're not as comfortable as they should be.  They are a little too large, but I feel a size down would be too small and hit against my toes.  These seem to have extra material above my toes which is stiff and buckles when I bend my foot.  This same thing has happened with other styles of Ryka I've tried. It may be time for me to switch to a different brand.
