Unisa Franci Leather Croc Trainers in Ivory. For the perfect nude pair of pumps we recommend the Franci style from Unisa. The Franci trainers feature a classic lace up fastening with metal eyelets and a round toe, but have the subtle twist of snake print details. The colour is perfect for pairing with all your favourite pieces and will work throughout the year. They're set on a chunky rubber sole and are so comfortable making them ideal for running errands or busy days.
