For this model in smooth leather, here's what to do:
First of all, arrange, apply a care cream to nourish the leather (the most important), then a brush stroke to shine it. Next, apply the same colour wax to the leather to revive its colour. And if you still have 30 seconds: waterproof to avoid rain and mud stains. We have everything we need in our shoemaker's shop at more than fair prices, don't hesitate.
And for your white sneakers, use the Coup d'éclat: a recoloring spray that nourishes and protects white leather.
