While the Hurricane Ridges are pretty supportive, that's not what I'm talking about. I picked these shoes because I wanted to support Montrail as they support the local trail running scene here in MN. Since I got the shoes for this reason, they have performed very well. I am replacing my Asic Trabucos and mainly wear them on the trails and to run to and from work in wet/snowy weather. A few weeks ago we got 9" of snow and, while I could have used snowshoes for the run home, they kept my feet nice and dry except the snow that got in the top (note: need gators). I also am recovering from a bout with PF and the support these shoes offer seems to be very adequate. My other shoes are Asic Kayanos and Brooks Beasts. One more thing, the shoes appear long and narrow but they fit great?!?
