Our Sofia mules are the perfect choice to combinate with your outfit in each moment, during the day or the evening. Keep yourself elegant but comfortable. Choose from three colours to co-ordinate with all your outfits. The Sofia Leather Mules are made in the Spanish town of Elche – a place renowned for its quality since the 19th century, and where many of the world's most famous luxury brands produce their leather items. La Portegna’s leather is vegetable tanned with a unique blend of natural tannins and colour compounds from Spanish flowers and tree bark. The leather is then treated with Spanish olive oil to nourish, soften and to make it more robust. This all-natural process has two benefits - it results in beautiful looking leather that develops a unique ‘patina’ over time – it quite literally gets better with age, and is unquestionably kinder to the environment, unlike the more commonly used chrome tanning processes.
