I purchased these new as chain spikes for icy conditions, but they were the wrong size, so I'm listing them without use. They are likely best for 23cm-25cm. (The shoes used for the photo are 24cm. Please refer to the photos.) Size: S Weight: 295g per piece Dimensions: Length 25.5cm x Width 9.5cm x Height 2cm Brand: Icer Materials: Sole: Synthetic rubber, Strap: Polypropylene, Nylon Spikes: Hardened steel Color: Black Manufacturer: Nissei Trading Co., Ltd. For snowy roads Removable anti-slip spike soles Simply attach them to your own familiar shoes. Size S: Length 25.5cm x Width 9.5cm x Height 2cm ★There are photos showing the measurements. It's best to check the outer dimensions of your shoes rather than your foot size. This is a simple yet reliable item that provides peace of mind.
