We offer three different size crampon toe bails: Narrow, Regular, and Wide. The Narrow bail fits narrow toe welts on newer-school leather ice boots and smaller sizes of these boots. The Regular bail fits regular toe welts, which are found on 80% of ice climbing boots today. The Wide Toe Bail fits wide toe welts, such as those on double plastic mountaineering boots and ski boots. If you are unsure which bail is right for your boots, please contact our customer service team.
