I had a long wait for my first order, which I was not aware was a "pre-order" that came with several delays while socks where shipping from overseas. But, when my sizing was off and I reached out to customer service, they exchanged half my order for a larger size, even after 4 months. I finally decided to reach out because I started seeing the ads pop up again and was upset enough about not being able to wear the constrictive socks.
