Sometimes zippers can become stiff. NEVER yank on a zipper; you risk destroying it! A super simple solution is to purchase "Zipper Lube". It's only $5 (on Amazon) for a tube and it can be used on literally ANYTHING with a metal zipper including jeans, dresses, gowns, handbags... as long as the zipper is metal, it will solve the problem!
Often shoes do not have "paper store tags" because the product information was on the box and the box is not present.
Sometimes shoes are supposed to come with extra laces or a bonus item. Sometimes the bonus item is not present.
Sometimes the pieces have been tried on in M*CYS. If the bottom of the shoe is dirty from being tried on, simply wipe with a Clorox brand wipe. MUST BE CLOROX BRAND. Other brands leave soap residue or can dye the product! NEVER use dollar store / family dollar brands.
Sometimes there could be a minor imperfection because it has been in stores and handled by customers.
