A few observations:

1. Vertical floral spray down the vamp makes up most, if not all, of the embroidery.  Exceptions exist, but they tend to be dated a bit earlier.
2. Single-color embroidery seems more common, but use of multiple colors does occur.
3. Fabric base color varies, some darker, some lighter
