Buckles should be on the outsideof your foot with any Crampons, gaiters or snowshoes. Buckles on the inside can trip you. The inside of your feet and legs should be smooth and free of catches
I have been of that theory. I took a glacier travel class a few weeks ago and the (deeply experienced) instructors suggested I swap on my crampons, based on the theory that if the straps are on the outside they can catch on the environment.
The comments in the article also seemed to be opposed to straps that run heel-toe bail-heel instead of just heel-ankle-heel (the latter seeming more common on newer step-in crampons.)
