How covert is staring at someone’s shoes trying to identify slight variations?

>>ferros+hz
Well, don't stare at them. You know in advance that your contact will be walking down Merriweather Lane at 11:30am. If his shoes sport a single "X" near the bottom, that means the dead drop has the microfilm ready for pickup. If it doesn't have that "X", then try again next Tuesday.

If you see two X's in his lacing, the package is at the alternate drop site.

If he has 3 X patterns, you're burned! Make your way to the safehouse after losing any potential tails.

Glance quickly, agent, and keep moving.

This setup reminds me of operation PIMLICO:

> Every Tuesday, shortly after 7:00, a British MI6 officer would take a morning stroll at the Kutuzovsky Prospekt in Moscow. He would pass outside a designated bakery at exactly 7:24 a.m. local time. If he saw Gordievsky standing outside the bakery holding a grocery bag, it meant that the double agent was requesting to be exfiltrated as a matter of urgency. Gordievsky would then have to wait outside the bakery until a second MI6 officer appeared, carrying a bag from the Harrods luxury department store in London. The man would also be carrying a Mars bar (a popular British candy bar) and would bite into it while passing right in front of Gordievsky. That would be a message to him that his request to be exfiltrated had been received.

That was poorly conceived. They'd have to keep those things stored somewhere for as long as the spy was active. What if a rat ate the last Mars bar at 6:00am?

Tell the rats that the Mars bars are off limits and they can stick to the Cadbury chocolates.
