I've worn them on plane trips THEY WERE AWESOME. I have never had pain in my legs and walked a total of 5 miles every day through major airports, cities and travel destinations. They breathe SO WELL, have enough support, we slip on and off easily and don't look terrible. It's not a stretchy material but they are breathable and hold up very well on my feet for what I used them for, light weight. Excellent purchase.
