If you don’t have the time or money to buy a second pair of shoes, you can change your brown shoes into black ones. Black leather shoe polish is a temporary fix if the shoes are leather. It darkens the sheen of the brown, and afterwards you can rub the polish off. Leather dye is a permanent change, and it should be used in conjunction with shoe polish to produce the best results.
Things You'll Need
Clean shoes properly with leather cleaner or shoe brush.
Apply black leather dye to your brown shoes with applicator. After it dries, apply a second coat of dye.
Polish shoes with black shoe polish with a sponge or rag and apply a second coat when the first dries.
