I love these foot socks. I have worn Avia for several years, and I love the soft, yet stretchy feel of them. They are not really heavy/thick, they are lighter, which is great for these hot summers. The Seller packed them in a sealed plastic bag and then placed the bag in a grey plastic mailer. The socks arrived ahead of schedule and were exactly as described. I will be back to purchase more, from this wonderful Seller. 5 STARS across the board. Thank you for a great purchase.
