The casual socks, have a padded sole. These socks are suited for casual wear and will fit nicely into your normal sized shoe. They are 85% alpaca and 15% nylon. I always wash my all my socks in the washer in cold water and lie flat to dry, and they are fine, but we must attach the following label..Hand wash in cool water, lie flat to dry. Beautiful socks! Please contact us with the order.......Coming Soon: Our service provider is working to incorporate an secure online payment service. Until such time we thank you for your patience.
