Size guide Mercury
Important sizing note: Our supplier uses an internal size-numbering system that may differ from the EU sizes listed here. The number stamped inside your shoes can therefore be different from the EU size selected at checkout. For example, Mercury men's EU 43 may have an internal 42 marking. Please use the US/UK/EU chart and insole measurements below to select the right fit.
