Is there a socket for SOP8 packaging with SOP8 pins?
You want an SOIC clip. You can use this to interact with the serial flash without desoldering.

These are also available on Ebay and from other sources
These will work on any SOIC package with matching lead spacing regardless of width (that winbond package is wider than the standard ones)
They also make them for 16 pin packages though those are much less common.
