Compression socks. I never have used them. Honestly didn’t think what is the big deal. And was blown away after taking them off. I honestly felt like they gave me a little bit of a boost of energy. I know it sounds weird. But I will always use them From now on when I travel. And I think they are going to make a great stocking stuffers for the family. LTKxPrimeDay LTKFamily LTKTravel
