OK... sounds like a confirmation of my AS sizing thoughts.
The main question for me is still whether a regular shoe stretcher (as they are reasonably easy to find and not so expensive) would fit a Chukka boot despite their high ankle.
Indeed that's one disadvantage of mail order. What I thought would be the best possible value for money hasn't lived up to that, yet. I haven't given up though, I'm hoping to stretch the left shoe. I think it should be possible.
I recently bought a pair of Chukka boots: Alfred Sargent Havant, to be found at http://www.pediwear.co.uk/sargent/products/1587.php
This was the first time ever for me to purchase shoes online. All my other shoes are in UK...
