The grip of the TrekSports is PHENOMENAL on snow. It felt like my feet had teeth that bit into the snow. I had no trouble with traction on any of today's snow, from hard-packed, to soft-packed, to loose fluffy snow. I walked some pretty steep uphill and downhill too and had no grip troubles.
I had decent traction on the frozen creek, too. Because the sun was shining, the smooth ice was a little tacky where it wasn't covered in snow.
It took about 1 km for my toes to warm up. Until then, my feet were a little uncomfortable. Once I and my feet warmed up, the run was very comfortable.
When I finished the run, my feet were wet but I don't know if it was from melted snow or sweaty feet. Either way, they weren't cold even after walking the last 10 minutes of my run.
I think I need to run the trails more, my feet felt a little weaker than usual but I haven't had much opportunity to run the trails since the snow fell. I'm looking forward to more of it now. I'm hoping for more (relatively) warm winter weather.
