Used for about two days during a trip. These are simple crampons that can be quickly attached over your shoes. Quantity: 1 pair (2 pieces) One size fits all, so anyone can easily put them on. They fold up compactly, making them convenient for carrying and storage. They provide a firm grip on snowy and icy roads, helping to prevent falls during commutes, trips to school, and outings. Will be sent via postal mail.
