In reply to billyf:
I've just dusted off my old Salewas - these are 'proper' 12 point crampons, and I'm planning to use them with my walking boots (which my Grivels won't fit onto), for the times when I don't want to be tramping around all day in stiff B2s on the off-chance that I might want to wear crampons for 10 minutes.
I seem to be taking bigger boots than when I last wore them, and the straps are now a bit short. Does anyone still sell the French-style ring bindings?
