Suede leather is used in a number of products, including upholstery, gloves, jackets, and handbags. Also used for shoes, probably the best known brand of suede shoes is Hush Puppies, made from pig hide. Suede shoes may also be made of doeskin and cow hide.
Suede shoes, because they have a nappy surface, scuff very easily. Scuffs can be difficult to clean, so it’s best to keep people and pets from stepping on them. But scuffed or not, suede is going to get dirty at some point and must be cleaned.
