I have spent months trying to find hoisery (with back seams) that didn't snag as soon as I put them on.  I LOVE the seam on these however with as much as women spend on one pair of tights/stockings/pantyhose, I would think that companies could find  a way to make these much less prone to snags.  I even put on lotion right before I put on any hoisery but for some reason every pair of seamed tights I buy snag.
