The K10's were up on South Sister at 10k strapped on to my Dynafit Pantera trail runners. With the low snow this year, they were on & off frequently as we crossed scree, early morning glacier ice and late afternoon slush at 30 degree angles. The K10's stuck in like glue, were easy to strap on/off and felt super secure. They'll be in my pack for early season Cascade volcano walk-up summits- a nice solution for those folks wanting more than Microspikes, but who cringe at carrying a full on crampon "just in case".
