<p>^ How do you know if big toe is causing the problem. Could it be that the little toe of one foot is causing the problem and the next time he wears that sock, it happens to be on the other foot, thus revealing that there is hole. If he wears that sock on the original foot, the hole would be on little toe and not reveal itself or that your H doesn’t care.</p>
<p>Have you labeled your H socks, L1x and R1, L2 and R2x where x= hole?</p>
