Traction crampons perfect for ski boots. - Brand: SIDAS - Model Name: Ski Boot Traction - Material: Rubber - Application: Crampons for ski boots - Design: Traction pattern Thank you for viewing. I used them only once, but I'm selling them because I no longer need them. They are in beautiful condition with no stains, but please note that the box is damaged. The instruction manual is also included. I think these will definitely be useful for the upcoming ski season. Please understand that these are stored by an individual and purchase accordingly.
