I already had a pair of these, but the silver bits were starting to peal off (don't put them through the dryer by accident!).
I like these compression tights - they are good both for running (flexible and light weight, and wick moisture away), as well as being flattering - the "X" pattern looks nicer than some other plain black running tights I have (i.e. it breaks up the black a bit). The latest version of these tights also has a little pocket on the inside waist band for a key which is a good addition.
They are pricey - but I like how they are shaped for a woman's body.
