The ICE-SPIKE, which can withstand temperatures down to -40℃, can be attached to shoes sized 22-25cm and provides a non-slip effect. I purchased it on Mercari and brought it with me on a trip, but I didn't have a chance to use it. It was opened upon purchase, but it is unused. - Size: M (22-25cm) - Cold resistance: Up to -40℃ - Product name: ICE-SPIKE - How to use: Easy to attach - Features: Non-slip effect Thank you for viewing.
