If you have worn Keen shoes before, the fit of the Saltzman is as expected.  I choose not to lace the last lug so it does not rub my ankle.  The Keen Dry does not breathe as well as non-waterproof materials, but should be fine in temperate or winter settings.  Grip of the sole seems great, but remains to be tested under slippery or icy conditions.  Have yet to try with orthotics.
