Ok, on further read (I forced myself) he put the socks on his feet. And was in the store. So how are they stolen?
Since he was naked, unless he had cash/credit in-hand (or elsewhere...Sorry), one could reasonably assume he was not intending to pay for the merchandise. Although it is possible he might have intended to shuck them prior to leaving, but who would expect to pay for the merchandise after he wandered around the store with them on? I'd support theft conviction if I was on a jury...
