These are a awesome to support my legs standing around the house and walking.  I got mild vericose veins with my second pregnancy and it's very uncomfortable without these tights.  They do however cause me to sweat and are a little uncomfortable on my belly.  They compress that area too.  Wish the belly area had more stretch.  They are a little harder to pull up but what do you expect?  Tey are supposed to be compressing.  My only gripes are the tighter area in the belly (I'm almost 7 months along) and how sweaty they make me under the belly.  They won't be wearable in the last month I'm sure but for now they serve the purpose great.
