How to measure for Sperry

Trace your foot on paper with your weight evenly distributed, mark heel to longest toe, and measure. Sperry's own guidance is to measure both feet and use the larger, and if you fall between sizes to take the LARGER size for toe room.

Sperry fit guidance

Sperry boat shoes are traditionally worn without socks and the leather relaxes and moulds to the foot with wear, so a new pair should feel snug but not painful. Sperry sells widths as S (narrow), M (medium, the standard), W (wide) and XW (extra wide) rather than by US letter — their own guide puts W at about 3mm wider across the forefoot than M, and XW about 6mm wider. Sperry notes the exact difference varies by style and last, and not every style is made in every width. Sperry's children's chart is keyed on Brannock millimetres — a true foot measurement — running from an 8.2cm infant foot to 25cm. Their infant and youth bands reuse US numbers, so band suffixes are shown here. No UK column is published for the children's range.
