The shoe itself is great, ..great for trails & sloppy weather & excellent traction in muddy wet conditions. However(!), I caution all "regular" Adidas running shoe fans to consider trying on a pair at a store before making the purchase. I never tried them on b/c usually all Adidas shoes fit almost the same. I have many pairs (Response Cushion, Response Trail, Adistar Cushion & Trail- all are a size 8). These are an 8 too, but feel like they could be a 7.5.  Except for the sizing inconsistency, The Kanadia is a light, flexible, well tractioned trail runner- good for "efficient" runners (probably wouldnt be good choice for those needing more stability). I would give it 5 stars, if it weren't for the sizing inconsistency.
