Omninettoyant is a special cleaner for suede, nubuck, crepe and textiles that removes stains. It also refreshes the original colour. Apply it with the small, silk-bristled wood brush that's included.
Remarks:
Our shoes tend to fit half size larger than most brands. Kindly size down from your usual EU/UK/US sizing. You may also consider how generous a fit you prefer - some like it snug and wait for it to break in, some like it loose with some space to wriggle around.
