The Strassburg Sock is a lightweight, breathable sock designed to wear while you sleep to fight plantar fasciitis. It’s designed to hold your plantar fascia in the perfect healing position without stretching your calves or pulling on your toes. It’s super simple and comfortable design is made for you to be able to sleep with it all night long in any position. Use: The Strassburg Sock is designed to be worn at night or during long periods of rest. For best results, they recommend you wear it for a minimum of six hours a night until you have 7 pain free mornings (specifically that sharp pain in the heel during your first few steps out of your bed). A research study showed that patients recovered in an average of 18 days with 98% of patients recovering within 8 weeks.
