These tights definitely helped with my swollen ankles throughout the day. I sometimes commute up to 3 hours per day (round trip) which leaves my ankles in a very swollen state. I also fly and these tights have helped. While at the end of the day, I'm still slightly swollen, the tights helped greatly since the swelling didn't spill over the sides of my shoes. I'm greatful to be able to do basic activities again without fear of severely swollen ankles at the end of the day.After two weeks of wearing them, they are still silky smooth and are durable since I've gotten no holes in them. It took a little practice to find a convenient way get them on after figuring out how to bend around my pregnant belly, but it's worth it.The only reason it gets 4/5 stars is that the top is a little tight around my belly and I'm only 6 months pregnant. The tightness leaves me huffing for breath after going for a walk since it makes it difficult to breath, but hurts when I fold it down. Despite the difficulties up top, I'll continue to wear them since they greatly help reduce my swelling. I'd definitely recommend this product to all those pregnant mommies suffering from swollen ankles.UPDATE: After wearing them until the completion of my pregnancy, I still highly recommend these tights. I wore them nearly every work day for four months and they only had a small worn hole at the crotch. No holes in the legs ever! With continued use the belly was still tight but did expand with my growing baby so I could continue to comfortably wear them until the end. I'll definitely be using them for my next pregnancy!
