GRIVEL-G10 crampons, black and yellow design, with straps for excellent stability. Wide model. Used with my climbing boots, Sirio 3E model. I think these are for those who find 12-point crampons to be overkill and want to save a little weight. - Model Name: GRIVEL-G10 - Color: Black/Yellow - Type: Crampons - Straps: Included - Condition: Used Thank you for looking.
