“I bought about 6 pairs of Swiftwick Aspire socks at least a decade ago as they were absolutely perfect in compression and support, for me. It is only now that they need replacing. The fabrication currently of this style has changed - they are softer, cozier, but missing the level of 'hug' from before, and there is a small tab in back even though they are still referred to as invisible (maybe so if wearing running shoes, but less versatile in this regard because the tab shows with other types of shoe).”
