EXCLUSIVE AT MR PORTER. Back in 1946, New England natives Daniel J. Wellehan Sr., William Beaudoin and Joseph Cordeau set out to make the shoes of the seaside – along came Sebago's 'Docksides', and the rest, as they say, is history. Inspired by the city of Portland, ME, these boat shoes are made from supple suede and set on anti-slip soles for enhanced traction.
