The dark-brown shade of Grenson's 'Lucas' Oxfords is the result of the brand's 'dipped' technique - once the shoes are cut and sewn, they're immersed in dye so the colour remains intact. This cap-toe pair is made from leather with matching linings and set on robust Goodyear-welted soles. Maintain them and they'll see you through a variety of formal and work-related occasions for years to come.
