I know this too well because the snowshoes that Cabelas sold me were crap that acted more like a snowboard. Why?
Take a good look at the bottoms in the next photo. The bottoms have a lot of slick surface to slide on and not much in the crampon category. Crampons being those metal teeth.
I had a miserable time with these shoes. They may be good for a day hike, but worthless for mountaineering.
BAD, REALLY BAD BOTTOMS
BETTER - SEE THE BIG RIDGES OF CRAMPONS?
THESE MSR'S ARE THE BEST - AGGRESSIVE EVERYWHERE AND CRAMPONS YOU COULD FELL A BIG, TALL SPRUCE WITH.
In addition to aggressive bottoms and crampons, the bindings should secure and remain secure. Mine, below, kept coming lose. Bad. Bad.
BETTER BINDINGS BUT MORE DIFFICULT TO SECURE
THESE MSR'S ARE THE BEST - SECURE AND EASY TO GET INTO AND OUT OF.
