Ice spikes to increase safety on ice and snow. Can be worn on sneakers, boots, and rain boots without non-slip features. I purchased these for a family business trip, but I am selling them because I didn't have the opportunity to use them. I have opened the package to check the contents, but they are unused. There are pin marks on the bag. - Size: L (25-28cm) - Product Name: ICE-SPIKE - Cold Resistance: Supports down to -40℃ - is-fit Thank you for viewing.
