These are truly comfortable tights. I can absolutely say that I frequently forget that I am wearing them, and they stay put all day without needing to be hitched up continually. They have a gentle shine, and are great for wearing under trousers. They are reasonably supportive, and definitely help my legs feel better by the end of my working day.
BUT...I have bought several pairs of XL, which according to the size chart is correct for me, and have had 2 pairs fail at the crotch seam after one wearing, so I will be buying XXL next time (and there WILL be a next time, as they are so good). The only problem with the XXL is that they are quite high-waisted on me. In short, wonderful, but buy a size above or risk disappointment.
L4M says, 'As neither we, nor the manufacturer, have had any other reports about this problem in the 560's (out of hundreds of pairs sold), we suspect that one of two things is happening; either Nick hasn't washed the 560's before wearing them (as recommended by the manufacturer on the packaging) as this frees up any fibres which may be 'stuck together' by residues from the dyeing process, and enables them to move more freely over each other, or he just needs the bigger size (just kidding!) ;0)'
