Hawkins Mountaineering Spats Gaiters ◼ Size ■ Color ■ Material ■ Please check the images. These are attached over boots with a string to prevent snow from entering. There were no instructions on how to attach them, so I tried them on. Please refer to the images. The sample shoe is 23cm. I bought these but never had a chance to use them, so they are in good condition. Thank you.
