You know, it really depends on the individual. Speaking broadly, I much prefer to see people in full-coverage, ankle-height footwear. I simply believe the support is better, the foot protection (especially in the sole) is better, and the traction is better. Trail-runners are聟trail-runners聴running shoes in drag. Compared with hiking boots, they聮re shorter, lighter, and have softer midsoles.
Black Diamond’s Contact Strap crampons

That said, plenty of people hike in trail-runners and do just fine. On good trails, with light loads, I聮d let the health of your ankles be your guide.
And sure, you can put crampons on trail-runners. What you need is a set of crampons with somewhat traditional straps. 聮s Universal XLC 490 crampons ($125) are moderately aggressive 12-point crampons with a strap system that allows them to fit over nearly any kind of footwear. They聮re also very lightweight, so they won聮t feel too clunky on trail-runners. 聮s Contact Strap crampons ($120) are nearly identical.
For slippery but non-technical snow, ice, or even steep grass, makes what聮s called an 聯instep” crampon聴think, crampons minus the toe points. The Crab 6 ($75) is a light six-point crampon that also will fit over most any shoe.
