With shoes like those shown below, when you adjust the buckle to the most tight position, the release handle is blocked (IMHO, this is due to bad engineering but cannot be changed.) Usually, this happens to me during several hour bike rides after readjusting, i.e. tightening the ratchet strap. As a result, I have to use tricks like inserting thin sheets of metal between the buckle and the strap, which is especially tricky in places where you do not have those devices around.
The major question is, how can I avoid this with my existing shoes? E.g. I was thinking of "inserting something" so that the most tight position is blocked.
However, I am also wondering whether I am the only one who experiences this problem, i.e. whether I am the problem, by e.g. buying shoes that are too large (by common standards, this is not the case) or by feet that shrink much more than average during pedaling.
EDIT: Regarding myself as a problem, I should add that due to a rare type of blood cancer, my blood is "thicker" (which is a physically incorrect term) than average, resulting in a bad (micro)circulation, especially during long exercise. Hence, an optimum solution would not increase the chance for unwanted heating, e.g. by wearing additional socks.
