I have been in aviation for 4 decades and never heard anything about non sparking shoes. I lot of those years was with aircraft, with engines that run on avgas! Never heard of and aircraft going up through static from sparky shoes. Guess there is a first time for anything and everything.
Perhaps its time you looked at CAO 20.9?
4.3.5 All footwear worn by aircraft servicing personnel and persons operating fuelling equipment shall be of a non-sparking type and such persons shall not carry any matches, cigarette lighters or other objects which could represent an ignition hazard.

Should I have been so near the fuel truck?
Under the circumstances that you describe, probably not!
