Went to Clarks today, and saw a wonderful pair of boots in the sale. I took myself off to a private corner to try them on, but I almost had an aneurysm attempting to pull the zip up. I have average sized feet (37) and normal ankles, but I have calves like parma hams. I have a pair of Duo boots that I rarely wear, as they crinkle round the ankle. I know there have been threads about this before, but I need someone with large calves to give me a personal recommendation. Can you get the leg bit of boots stretched? If so, where do you get it done?
