  • Nice shoe, but not typical Keen width

    2

    This shoe is nice, but definitely not wide enough - especially considering the many other keens I have owned throughout the years (I purchased the "wide" size). I own the CSA Rossland, which the geometry of the toe is much more accommodating - but I needed something lighter - so, I tried the San Antonio. Unfortunately, the aluminum toe in this shoe is narrow and comparable to a standard run-of-the-mill safety toe. Definitely not what I need. My suggestion to Keen is a redesign of the the aluminum toe. Make sure the geometry on the inside - where the big toe goes - is straight, not tapered towards the other toes.
