This is my second Clark's. The first Un. Ravel was great from Day One. This one felt fine wearing it at home the first day, but the next day when I wore it outside and walked less than two miles, I had to take if off because it was rubbing the right heel to the point that it became very painful to wear.

I fixed the problem by by wetting the heel grip and using a shoe tree to press it smooth, and by wearing heavier socks.

As for the construction quality: the tongue on the left shoe is off-center; the two seams from toe to eyelets on left shoe are visible -- not hidden as on right shoe; the outside left shoe eyelet piece is wider than on the right shoe.
