The OS1st Toe Spacers are designed to gently comfort bunions, hammer toe, and hallux valgus. We recommend using the toe spacers as a resting therapy before or after activity, during activity for prevention and performance, and as needed for comfort. Made of a soft, durable, and flexible rubber, the OS1st Toe Spacers are designed to be a comfortable toe spacing option. The toe spacers come in a pack of 4. We recommend that you hand wash the spacers with mild soap and let them air dry.
