Vintage Leather Zamberlan Men's Walking Boots 11

Hi... These Zamberlan Mens Walking Boots are size 11, in excellent condition as noted by the pictures. I have them for six months but unfortunately the size 11 is a little too big for me, where as the size 10.5 is a perfect size. There was very little use of these boots by me. I am a Walk Leader with a Walking Club & would not sell Walking Boots if I thought there was an issue with them, its about personal safety on the Mountains.
