This is a set of two anti-slip shoe spikes purchased at ABC-Mart during a trip to Hokkaido the day before. I carried them in my backpack just in case, but I never had the opportunity to use them. They have been opened, but are unused. I will sell both items together to someone who needs them. How about them for winter snow and icy road対策? Ice spikes to enhance safety on ice and snow, size M (22-25cm), compatible down to -40℃. - Brand: is-fit - Model Name: ICE-SPIKE - Size: M (22-25cm) - Cold Resistance: Compatible down to -40℃ Thank you for looking.
