I bought my first pair of these six years ago while in vacation, and am still wearing them! Like others, I get the insoles wet, add soap, and scrub them with an old toothbrush quite often, and they have held up well. I decided it was time to see if they were still being made, and to get some in other colors. So, I ordered two more pair! The design has slightly changed, but they are still wonderful. I struggle with bunions and occasional plantar fasciitis, and these shoes are great for helping with those issues. My only complaint, be it ever so slight, is that they do run a bit small. I normally wear a 7 or 7 1/2 Wide, and these are an 8 M. I think, in time, the leather will stretch a bit, but I've noticed that the "big toe" part of the shoe is fairly tight. Other than that, these shoes are perfect. Thanks, Columbia, for continuing to make this great and comfortable design!
