I run trails all year round. Mud, ice, rain, snow, slush, etc..  No shoe will keep you dry but these are better than most - so I continue to purchase them. This winter, there has been a lot of back and forth of rain and freezing and build up on the trails is dense. I would normally avoid these trails if it were not for these shoes. Nothing is perfect for packed snow and ice, but these perform well. I noticed that after running through a 5 or 6 inch deep puddle for 20 steps or so that the shoes clean up quickly upon getting back to land - so the treads are well designed. There are a variety of colors too...
