Over Shabbat someone told me they read in Meorot HaDaf Hayomi (מאורות הדף היומי) a while back that there is some problem with tucking the tzitzit into ones belt (he said something about heflesk maybe). He was referring to specifically tucking them in from the top, and then letting them dangle from the bottom. I know that many people such as Rabbi Aharon Lichtenstein where their tzitzit wrapped around the belt form the outside in, though I fail to see how that would be different.
Anyone know anything about this?
