In reply to sabostar:
6.5 and 9 here.
Climbing shoes, two pairs.
Walking boots, one pair, with superfeet insoles (oddly corrected to superferret...) and the smaller fit lifted with another insole.
Also thirty plus years of trogging about in ill fitting boots means the sole of that foot is incredibly (and I mean extraordinarily) thick.
And due to the odd shape of my feet (let's say it was an industrial threshing accident) and years of wearing supported arch inserts means that both feet are more or less identically shaped around the ankle,but I mainly have shorter toes
