Hi. Thank you for your advice. Had not come across these versatile crampons, despite three evenings of non-stop research. It's amazing how much you need to know, and how much you need to 'speak' to a multitude of people to learn!
Okay, so I have looked at the KTS crampons. They look spot on. Do you think the Black Diamond Contact Strap is pretty much the same thing as a KTS? (Just asking as that is in stock in a very local store.)
As for footwear, I didn't really know what to wear. Was just planning on wearing my Merrell approach shoes that are super light and super comfy, and did me very well in Wales, but it was my partner that said, "No! You must have big Winter boots!"
I just spoke to someone working at Glenmore Lodge and he said he would wear approach shoes rather than high-top boots, just as a personal preference. (I am painfully aware that as the second I have to carry all this stuff on my back for both climbers, two pairs of shoes/boots, two sets of crampons, ice axes, plus water/food, etc, so a pair of lightweight approach shoes seems far more appealing to me!) Another factor in footwear is that we have a two-and-half-hour walk in, so don't really want to be in huge winter boots for that.
So, so far, Anonymous, the idea of crampons that attach to approach shoes seems like a tip-top idea!
