After years of playing tennis, my muscular calves prevent me from fitting into most high-street boots. Duo are my saviour - the boots are made to measure both foot and calf size. At £180 they are not a budget buy, but considering they are made to order, the cost-per-wear comes way down. I wore mine for the first time last night and they were the height of comfort even walking a couple of miles on a round trip from Camden to Kentish Town.
