  • Not the Keen Bostons of Years Before, going DOWNHILL

    3

    I have had four previous pairs of the Keen Bostons. The first three pair were great! However the last two pairs have not even been close in quality and construction. I think Keen is cutting a lot of corners to make the shoes cost them less to make, but yet charging the customer the same or more. Gone is leather interior (as pictured), the soft but durable shoelaces, soft and flexible leather, and even the toe cap is smaller and differently shaped. I think this will be my last pair of Keen Bostons. I love the older versions and the older version really hold up, however the new versions are nothing like the old ones, except when viewed across a room. It is shame that Keen ruined a great shoe to save a few dollars. I wish i could buy the old Boston IIs, that was the last great version of this shoe!

    I own 9 pairs of Keens — and these by far my favorite. Very stable, cushioned, and great looking.

    I wear these at work in a hospital environment and have for many years. They will last forever although the laces will eventually wear out but keen will usually replace them. I've actually like these so much that the pair I have recently purchased is my back-up should they possibly discontinue them. I BELIEVE I currently have the original Bostons and so far they have lasted at least 7 years. These are the Boston III. Eventually my originals will wear out? When they do, these are my back-ups.

    although the shoestrings were substantial they wore out before the shoes. The soles on first two pair wore out on the tread. The 3rd pair has fabric interior, I prefer the leather interior and different soles. My second pair had frayed inseam down middle of shoes.

    I have hard to fit feet and have had a knee replacement and a hip replacement. Stable, somewhat wide, and comfortable shoes, like these, are important to me being active. These shoes do what I need done.
