I'm taking a mountaineering course this summer and D-type boots are required. I plan on renting them on location. Not optimal but frankly I don't have the cash for new D-type boots.
Now, I do have Grivel Airtechs with a new classic (the classic strapon) binding that I used on previous trips, in combination with B/C boots.
Question is; will those Airtechs with the new classic binding fit most D-type boots?
